1. Definitions and interpretation
1.1 “Aqua Works”, “we”, “us” and “our” mean Pure Water Services North Limited, trading as Aqua Works and Warkworth Plumbing, including its employees, authorised agents and subcontractors.
1.2 “Customer”, “you” and “your” mean the person or entity requesting, ordering or accepting the Works. Where there is more than one Customer, each is jointly and severally liable. A person ordering on behalf of an owner, trust, company or other entity warrants that they have authority to do so. If you contract as a trustee, you are bound in that capacity, and the Contract extends to your right of indemnity from the trust’s assets.
1.3 “Works” means all goods, materials, equipment, labour, services, design, investigation, diagnosis, hire, installation, testing, commissioning, maintenance, repair and related work supplied by us.
1.4 “Contract” means these Terms together with the one-page Terms of Trade printed with our quotations, the accepted quotation, scope, work order, variation, invoice, credit application and any other document expressly incorporated into the agreement.
1.5 “Business Customer” means a Customer acquiring the Works in trade for the purposes of a business. “Consumer Customer” means a Customer acquiring goods or services ordinarily acquired for personal, domestic or household use and not validly contracting as a Business Customer.
1.6 Headings assist navigation and do not limit interpretation. “Including” does not imply limitation. References to legislation include amendments and replacement legislation.
2. Application and acceptance
2.1 These Terms apply to all Works supplied by us unless a written agreement signed by an authorised representative of Aqua Works expressly states otherwise.
2.2 You accept the Contract when you sign or electronically accept a quotation, instruct us to proceed, book a service, approve a variation, pay a deposit, accept delivery, or permit us to begin the Works.
2.3 Our Contract prevails over any terms supplied by you unless we expressly agree in writing to those terms.
2.4 Electronic communications, electronic signatures and electronic acceptance may be used to form and administer the Contract to the extent permitted by the Contract and Commercial Law Act 2017.
2.5 If there is inconsistency, the order of priority is: a signed special agreement; the accepted quotation and written variations; the one-page Terms of Trade printed with the quotation; these Terms; then other Contract documents.
3. Quotations, estimates and scope
3.1 Unless stated otherwise, quotations are valid for 30 days and may be withdrawn or revised before acceptance.
3.2 A quotation is based on the information available and conditions reasonably visible when prepared. An estimate is an indication only and the final charge will reflect the actual time, materials and costs reasonably incurred.
3.3 Fixed-price work includes only the items expressly described in the quotation. Work not expressly included is excluded, even if it is necessary to complete a wider project.
3.4 Prices are in New Zealand dollars and exclude GST unless expressly stated otherwise.
3.5 We may correct an obvious clerical, typographical or arithmetic error. If the correction materially changes the Price, you may cancel the affected unperformed portion without penalty.
3.6 Unless included in the quotation, the Price excludes council fees, permits, producer statements, engineering, electrical work, specialist testing, access equipment, traffic management, service locating, excavation, spoil removal, asbestos work, painting, building work and reinstatement.
4. Diagnosis, investigation and call-outs
4.1 Time spent travelling, attending, diagnosing, testing, disassembling, cleaning, locating a fault, preparing advice or obtaining technical support is chargeable whether or not a repair proceeds or the fault can be conclusively identified during the visit.
4.2 A diagnostic opinion is based on the symptoms and conditions observable at the time. Intermittent faults, concealed defects and multiple contributing faults may require further investigation.
4.3 Emergency, after-hours, weekend and public-holiday work may be charged at our applicable call-out and penalty rates. Attendance times are estimates and may be affected by staff availability, travel and other emergencies.
5. Variations and unexpected conditions
5.1 A variation includes any change to the scope, quantity, method, timing or sequence of the Works, and any additional work required because of hidden, unsafe, defective or unexpected conditions.
5.2 Examples include concealed pipework or wiring, corrosion, non-compliant work, restricted access, rock, groundwater, unstable ground, asbestos, inaccurate plans, unavailable services, defective existing systems and prerequisite work not being completed.
5.3 We will seek approval before carrying out a material variation where reasonably practicable. Approval may be verbal, written or electronic. If urgent work is reasonably required to prevent injury, contamination, flooding, property damage or loss of essential water or sanitation, we may carry it out without prior approval and charge a reasonable amount.
5.4 Variations are charged at the agreed rate or, if no rate is agreed, at our current labour, material, plant and subcontractor rates plus applicable margins and GST.
5.5 A variation may extend completion dates and alter other parts of the programme.
6. Price and payment
6.1 Unless the quotation or invoice states otherwise: jobs with a Price of $1,000 or less are payable on completion; jobs over $1,000 require a 40% deposit before ordering or scheduling; and the balance is payable within 24 hours of completion or invoice.
6.2 We may require different deposits, progress payments, payment before delivery, staged payments or approved credit terms. The payment terms shown on the quotation or invoice prevail.
6.3 Deposits may be applied to materials, mobilisation, design, administration and reserved capacity. A deposit is not necessarily refundable if you cancel after we have incurred costs or committed resources.
6.4 You must pay the undisputed portion of an invoice by the due date. A genuine dispute about one part does not entitle you to withhold unrelated amounts, subject always to rights that cannot lawfully be excluded and the Construction Contracts Act 2002 where it applies.
6.5 Card or third-party payment charges may be passed on where disclosed and permitted by law.
6.6 We may allocate payments against any amount owing, acting reasonably and subject to applicable law.
7. Progress payments and the Construction Contracts Act
7.1 Where the Construction Contracts Act 2002 applies, we may issue payment claims and you must respond with a valid payment schedule within the statutory or agreed time if you do not intend to pay the claimed amount in full.
7.2 We retain all statutory rights to recover unpaid claimed or scheduled amounts, refer disputes to adjudication, and suspend construction work after giving the notice required by the Act.
7.3 Nothing in the Contract is intended to contract out of the Construction Contracts Act where contracting out is prohibited.
7.4 Retention money applies only if expressly agreed in writing. Where statutory retention-money provisions apply, the party withholding retention money must hold, account for and report on it as the Act requires.
8. Overdue accounts and debt recovery
8.1 Interest accrues on overdue amounts at 2% per calendar month, calculated daily and not compounded, from the due date until payment. For Consumer Customers, interest and fees will be applied only to the extent they are reasonable and enforceable.
8.2 You must reimburse our actual and reasonable costs of recovering overdue amounts, including collection-agency charges, court filing fees and legal costs, to the extent permitted by law.
8.3 We may suspend further work, decline further credit, require payment in advance, or cancel unperformed work where an amount remains overdue or we reasonably consider your credit risk has materially increased.
8.4 Suspension or cancellation does not affect accrued payment rights or your liability for reasonable demobilisation, storage, remobilisation and cancellation costs.
9. Customer responsibilities and site access
9.1 You must provide timely decisions, accurate information, safe and unobstructed access, suitable parking and working space, and access to water, power and sanitary facilities where reasonably required.
9.2 You must ensure the owner, occupiers, tenants, body corporate and other affected persons have authorised the Works and have been told about interruptions, access and safety requirements.
9.3 Children, animals and unauthorised persons must be kept clear of the work area.
9.4 Unless agreed otherwise, you are responsible for moving furniture and belongings, protecting sensitive items, and providing clear access to tanks, pumps, roofs, ceilings, underfloor spaces and service routes.
9.5 Extra time caused by inadequate access, waiting, aborted attendance or a site not being ready may be charged.
10. Plans, underground services and concealed conditions
10.1 You must disclose and accurately identify known underground, concealed or overhead services, including water, drainage, gas, electricity, communications, irrigation, septic and pumping lines.
10.2 We will take reasonable care but cannot guarantee avoidance of services that are incorrectly shown, unmarked, non-detectable or installed contrary to normal practice.
10.3 You are responsible for reasonable loss and cost arising from inaccurate or incomplete information you provide, except to the extent caused by our negligence or breach of law.
10.4 We may require a professional service locator, engineer or other specialist at additional cost before excavating, cutting or drilling.
11. Health, safety and hazardous materials
11.1 We may stop, refuse or postpone work where we reasonably consider conditions unsafe, unlawful or likely to expose people, property or the environment to unacceptable risk.
11.2 You must disclose known asbestos, contaminated soil, hazardous substances, biological hazards, confined spaces, structural instability and other site risks.
11.3 Discovery of asbestos or another hazard is a variation. We do not remove or disturb hazardous material unless this is expressly within scope and is carried out by appropriately competent people.
11.4 You must comply with reasonable site safety directions and must not operate or alter incomplete work or safety controls.
12. Delivery, storage, title and risk
12.1 Delivery occurs when goods are delivered to the site or other agreed address, made available for collection, or taken by your carrier.
12.2 Risk in goods passes on delivery. For goods we install, risk in the installed Works passes on completion of the relevant stage, except to the extent loss is caused by us before leaving the site.
12.3 Ownership of goods does not pass until all amounts owing for those goods and their installation have been paid in cleared funds.
12.4 Until ownership passes, you must keep identifiable goods secure and insured and must not sell, dispose of or grant security over them except in the ordinary course of business.
12.5 Subject to law, if payment is overdue we may recover goods that have not become fixtures, provided entry is lawful and undertaken reasonably.
12.6 If delivery or installation is delayed by you, we may charge reasonable storage, handling, redelivery and remobilisation costs, and risk passes when the goods are placed into storage for you.
13. Personal Property Securities Act 1999
13.1 These Terms constitute a security agreement. You grant us a security interest in goods supplied by us, their proceeds, and any associated account receivable, to secure all amounts you owe us in relation to those goods and Works.
13.2 You must provide information and sign documents reasonably required to register, maintain, amend or discharge a financing statement on the Personal Property Securities Register.
13.3 You must reimburse reasonable registration and discharge costs.
13.4 To the maximum extent permitted by section 107 of the PPSA, the parties contract out of sections 114(1)(a), 133 and 134, and you waive the rights listed in section 107(2), including the right to receive a verification statement under section 148, except where contracting out or waiver is prohibited or inappropriate for consumer goods.
13.5 We will exercise PPSA rights in good faith and in accordance with reasonable standards of commercial practice.
14. Existing systems, pipework and property
14.1 Our Price assumes existing structures, plumbing, drainage, electrical systems, tanks, pumps, controls and connections are serviceable, compliant and suitable unless the quotation states otherwise.
14.2 Old, corroded, brittle, undersized, poorly supported or non-compliant components may leak or fail when disturbed, repressurised, reconnected or placed under normal operating load. Repair of those components is a variation unless caused by our failure to exercise reasonable care and skill.
14.3 Restoring pressure or flow can expose pre-existing leaks, weak fittings, blocked outlets, water hammer or defects elsewhere. We are not responsible for a pre-existing defect merely because it becomes apparent after our work.
14.4 Cutting, excavation and access work may unavoidably affect lawns, paving, walls, cabinetry, finishes and landscaping. Reinstatement is excluded unless expressly included. We will take reasonable care to minimise damage.
14.5 We do not warrant the performance of parts, systems or work supplied or altered by others.
15. Customer-supplied products and third-party work
15.1 If you supply a product, we are responsible only for our installation workmanship, not the product’s quality, compatibility, completeness, instructions or warranty.
15.2 Additional time caused by missing, unsuitable, defective or incompatible customer-supplied products is chargeable. Removal and refitting may also be chargeable unless our installation was defective.
15.3 We may refuse to install a product that appears unsafe, non-compliant, unsuitable or unsupported in New Zealand.
15.4 Work dependent on builders, electricians, drainlayers, engineers, councils, suppliers or other third parties may be delayed. We are not responsible for their acts or omissions unless they are our subcontractors.
16. Pumps, bores, tanks and water sources
16.1 Pump selection and system design rely on information about source level, bore depth and yield, pipe size and length, elevation, required flow, electrical supply, tank capacity and intended use. You must disclose accurate information and material changes.
16.2 We do not guarantee the continuing yield, level or quality of a bore, well, stream, spring, rainwater catchment or other natural source. Drought, seasonal change, contamination, silting and neighbouring abstraction may affect performance.
16.3 A pump cannot supply water that is not available. Damage or interruption caused by dry running, loss of prime, blocked strainers, empty tanks, suction leaks, closed valves, frost, flood, lightning, voltage irregularity or contaminated water is not a workmanship defect unless caused by our work.
16.4 Existing suction lines and buried pipework cannot always be fully assessed. Temporary surface pipework or other testing may be recommended to isolate a fault.
16.5 Pump duty, pressure and flow figures are design targets based on supplied information and normal tolerances, not guarantees of identical performance at every outlet or under every operating condition.
16.6 Electronic pumps, controllers and UV systems should be protected by suitable electrical surge protection. Electrical supply faults and surge damage are excluded from our workmanship warranty.
17. Water treatment and drinking-water systems
17.1 Treatment equipment is designed for the raw-water characteristics, flow, usage and performance objectives identified at the time of design. Changes in source water or use may require further testing, adjustment or additional treatment.
17.2 Any removal rate, contaminant reduction, water-quality result, flow, pressure or output figure given in a quotation, proposal, email, conversation or manufacturer’s data sheet is a design estimate, not a guarantee, unless the quotation expressly states a guaranteed result together with the test method and sampling point. Manufacturer ratings, such as a membrane’s salt rejection, are measured under standard test conditions and do not predict the removal of a particular contaminant from your water.
17.3 Unless expressly guaranteed in writing against stated test parameters, no treatment system can be represented as making every possible source safe in every circumstance.
17.4 Sediment filters, carbon media, UV lamps, quartz sleeves, softener resin, salt, membranes, dosing chemicals, seals and similar items are consumables. Their life varies with water quality and use.
17.5 You are responsible for maintaining the source, tanks, roof catchment, gutters, screens, pipework and treatment system, and for arranging servicing and consumable replacement at the intervals we or the manufacturer recommend.
17.6 Unless a different interval is specified, treatment systems must be inspected and serviced at least every 12 months. More frequent service may be necessary for high use or poor water quality.
17.7 UV performance depends on flow, UV transmittance, turbidity, lamp output, sleeve cleanliness and correct installation. Water downstream may require flushing or disinfection after contamination, prolonged shutdown or loss of UV protection.
17.8 A laboratory result relates only to the sample, location and time tested. We are not a laboratory and do not guarantee ongoing potability from a single sample.
17.9 Where a supply is subject to the Water Services Act 2021, Drinking Water Standards, Drinking Water Quality Assurance Rules or another regulatory requirement, responsibility for supplier registration, compliance planning, sampling, records and ongoing operation remains with the legally responsible drinking-water supplier unless expressly included in our scope.
18. Temporary water supplies and interruptions
18.1 Plumbing and water-system work may require temporary shutdown, draining, isolation or reduced pressure. You must make suitable arrangements for occupants, animals, businesses and processes that require continuous water.
18.2 A temporary tank or bypass is a limited short-term service. Capacity, water quality, flow and resilience may be lower than the permanent supply. You must monitor water level and promptly report leaks, pump cycling, loss of prime or contamination concerns.
18.3 Unless expressly included, we do not provide continuous monitoring, water cartage, emergency replenishment or backup power.
19. Compliance, consents and regulated work
19.1 We will perform our Works in accordance with applicable legal requirements and the accepted scope. Regulated plumbing, gasfitting or drainlaying will be performed or supervised as required by the Plumbers, Gasfitters, and Drainlayers Act 2006.
19.2 Building consent, resource consent, network approval, engineering design, electrical certification, backflow compliance, specified-system documentation and council inspection are excluded unless expressly included.
19.3 Where existing work is unsafe or non-compliant, we may be unable to reconnect or certify it without remedial work.
19.4 We will not knowingly carry out a customer instruction that is unlawful or materially unsafe. Recording a customer’s preference in writing does not permit departure from mandatory requirements.
20. Timing, delays and force majeure
20.1 Dates and attendance windows are estimates unless expressly agreed as fixed. We will use reasonable efforts to meet them.
20.2 We are entitled to a reasonable extension for variations, adverse weather, supply shortages, transport disruption, illness, emergencies, council or utility delay, industrial action, site conditions, customer delay, or any event beyond our reasonable control.
20.3 We are not liable for delay loss to the extent caused by such events, but this clause does not excuse payment for Works already supplied or remove rights that cannot lawfully be excluded.
21. Completion, commissioning and handover
21.1 Works are complete when they are substantially complete and capable of their intended use, despite minor defects, documentation or adjustments that do not materially prevent use.
21.2 You must inspect the Works and promptly notify us of any apparent issue. For Consumer Customers, failure to notify promptly does not remove statutory rights, but delay may make cause and remedy harder to determine.
21.3 You must follow operating, maintenance, safety and shutdown instructions and ensure they are passed to owners, tenants, staff and future operators.
21.4 We may photograph or record equipment, serial numbers, site conditions and completed work for job, safety, warranty and quality records. Marketing use that identifies a person or private property requires appropriate permission.
22. Workmanship warranty and manufacturer warranties
22.1 We warrant our workmanship for 12 months from completion and will, within a reasonable time, investigate and remedy a workmanship defect notified within that period.
22.2 This express warranty is additional to statutory rights and does not limit any guarantee or implied warranty that cannot be excluded.
22.3 Goods are covered by the manufacturer’s warranty, if any. We will reasonably assist with a valid claim, but manufacturer assessment, freight, access, removal, refitting and consequential labour may be chargeable unless we or the manufacturer are legally responsible for those costs.
22.4 Warranty does not cover fair wear and tear, consumables, misuse, accident, contamination, freezing, flooding, vermin, vandalism, fire, lightning, power surge, abnormal voltage, dry running, blocked filters, lack of salt, failure to service, use outside design conditions, changes in source water, or alteration by others.
22.5 Warranty may be declined to the extent an issue was caused or worsened by failure to follow instructions or maintain the system. A blanket annual-service condition will not be used to exclude an unrelated statutory claim.
22.6 Where system pressure may exceed the equipment rating or 551 kPa, suitable pressure control must be installed. UV and electronic equipment should have suitable surge protection. Failure to maintain these protections may affect claims caused by excess pressure or electrical events.
23. Consumer rights and residential building work
23.1 Nothing in the Contract excludes or limits the Consumer Guarantees Act 1993, Fair Trading Act 1986, Building Act 2004 or any other right that cannot lawfully be excluded.
23.2 Where the Consumer Guarantees Act applies, goods and services carry the statutory guarantees, including acceptable quality, fitness for disclosed purpose, reasonable care and skill, and completion within a reasonable time where no time is fixed.
23.3 Where the Building Act implied warranties for residential building work apply, they apply despite contrary wording in the Contract.
23.4 Any limitation, exclusion, time limit or remedy in these Terms is subject to this section.
24. Business-to-business contracting out
24.1 Where you acquire the Works in trade and both parties are in trade, the parties agree in writing that the Consumer Guarantees Act 1993 does not apply, and that sections 9, 12A and 13 of the Fair Trading Act 1986 do not apply, only to the extent contracting out is legally permitted and it is fair and reasonable for the parties to be bound.
24.2 This section does not exclude liability for fraud, wilful misconduct, misleading conduct that cannot validly be contracted out of, or any obligation that law prohibits the parties from excluding.
24.3 You acknowledge that you have had a reasonable opportunity to review and negotiate the Contract and obtain independent advice.
24.4 You rely only on the accepted quotation, any signed variation, the one-page Terms of Trade and these Terms. You do not rely on any other statement, representation or estimate unless it is written into the quotation.
25. Liability
25.1 For Consumer Customers, our liability is governed by applicable consumer law and this section applies only to the extent permitted.
25.2 For Business Customers, to the maximum extent permitted by law, neither party is liable to the other for indirect or consequential loss, loss of profit, loss of production, loss of data, loss of opportunity or business interruption.
25.3 For Business Customers, our aggregate liability arising from the affected Works is limited to the Price paid or payable for those Works, except for liability that cannot lawfully be limited, and except for fraud or wilful misconduct.
25.4 We are not liable to the extent loss is caused by your act or omission, inaccurate information, a pre-existing defect, failure to mitigate loss, third-party work, or use outside the agreed purpose.
25.5 Each party must take reasonable steps to minimise avoidable loss.
26. Cancellation and suspension
26.1 You may cancel unperformed work by written notice. You must pay for Works performed and reasonable costs already incurred or irrevocably committed, including special-order goods, restocking, design, administration, demobilisation and lost non-recoverable booking costs.
26.2 A cancellation charge must reflect our reasonable loss and is not a penalty. We will credit costs we reasonably avoid or recover.
26.3 Special-order, custom-made, opened, installed or used goods cannot be returned for change of mind. Standard unused goods may be accepted by prior written agreement, subject to condition, return freight and a reasonable restocking charge.
26.4 We may suspend or cancel unperformed work for non-payment, unsafe conditions, unlawful instructions, material breach, insolvency or a reasonable loss of confidence in your ability to pay, after notice where notice is reasonably practicable or legally required.
27. Privacy, credit checks and communications
27.1 We collect, use, store and disclose personal information in accordance with the Privacy Act 2020 for quoting, supplying Works, account administration, health and safety, warranty, credit assessment, debt recovery, legal compliance and customer communication. Pure Water Services North Limited, 2 Mill Lane, Warkworth 0910, collects and holds this information.
27.2 We may collect information about you from other people, such as builders, property managers, real estate agents, referees and credit reporters. Where we do, this clause is our notice to you of that collection. We may disclose relevant information to credit reporters, referees, insurers, suppliers, subcontractors, professional advisers, debt-collection agencies and government authorities where reasonably necessary and lawful.
27.3 You may request access to, or correction of, personal information we hold about you. We may retain records for legal, tax, warranty, safety and business purposes.
27.4 If a privacy breach is notifiable, we will notify the Privacy Commissioner and affected individuals as required by the Privacy Act 2020.
27.5 Marketing electronic messages will be sent only as permitted by the Unsolicited Electronic Messages Act 2007, and you may unsubscribe.
27.6 Our website Privacy Policy at aquaworks.co.nz/privacy-policy explains how we use cookies and analytics.
28. Intellectual property
28.1 Unless agreed otherwise, we retain copyright and other intellectual property in our designs, drawings, calculations, schedules, templates, reports and methods.
28.2 After full payment, you receive a non-exclusive licence to use project-specific documents for operating, maintaining and completing the particular project, but not for resale, replication on another site or commercial exploitation.
28.3 You warrant that material and instructions you provide may lawfully be used and do not infringe another person’s rights.
29. Complaints and disputes
29.1 Please raise concerns promptly with Aqua Works so we have a fair opportunity to inspect and remedy an issue.
29.2 The parties will first attempt to resolve a dispute through good-faith discussion. This does not prevent urgent court relief, a statutory complaint, debt recovery, or adjudication under the Construction Contracts Act.
29.3 A construction dispute may be referred to adjudication where the Act applies. Other disputes may be referred to mediation by agreement.
29.4 Consumer Customers retain access to the Disputes Tribunal, courts, regulators and other statutory remedies. Arbitration applies only where separately agreed and legally enforceable.
30. General
30.1 The Contract is governed by New Zealand law. The New Zealand courts have jurisdiction, subject to statutory tribunals and adjudication rights.
30.2 We may use suitably qualified subcontractors and remain responsible for our contractual obligations.
30.3 You may not assign the Contract without our written consent, not to be unreasonably withheld. We may assign receivables or transfer the Contract as part of a genuine business restructure or sale, provided this does not materially reduce your rights.
30.4 If a provision is invalid or unenforceable, it is modified to the minimum extent necessary or severed, and the remaining provisions continue.
30.5 A failure or delay in enforcing a right is not a waiver.
30.6 Changes to these Terms apply only to future Contracts unless both parties agree otherwise. The version accepted with a Contract remains applicable to that Contract. We keep a copy of each version we issue.
30.7 Notices may be delivered personally, by post or by email to the latest contact details supplied. Email is treated as received when it enters the recipient’s information system, unless the sender receives a delivery-failure notice.
