Renovation Contract Checklist NZ: What to Check Before You Sign

1. Check who you are actually contracting with

Start with the legal name in the contract.

You need to know whether you are contracting with an individual, partnership, company or another legal business entity. This matters because that is the person or organisation responsible for performing the agreement.

The contractor's disclosure statement can also help you check the business identity, key contact, relevant skills and qualifications, and information about insurance or guarantees being offered.

Before signing, make sure the contract details match the business you believe you have hired. If the contracting party or the person responsible for running the work is unclear, get that clarified first.

If your contractor due diligence is not complete, use SeekSaver's Questions to Ask a Builder Before a Renovation NZ before signing.

2. Make sure the scope matches what you agreed

The contract should clearly describe the work.

For contracts covered by the prescribed minimum-content rules, it must also identify relevant materials and products where known and say who will carry out or supervise the work.

Compare the contract with your:

• renovation brief;
• quote or proposal;
• plans and drawings;
• specifications;
• product or material selections.

Pay particular attention to exclusions, assumptions and attachments.

If a drawing, schedule or specification is referred to in the contract, make sure the correct version is actually included in the contract package.

A useful test is:

Could someone unfamiliar with your earlier conversations understand what the builder has agreed to do by reading the signed contract package?

If not, the scope probably needs more clarification.

If the scope itself is still unclear, return to SeekSaver's Home Renovation Project Brief Checklist NZ before signing.

3. Check who is responsible for consents, inspections and project tasks

Do not rely on a general statement such as “the builder will handle everything”.

For contracts covered by the statutory minimum-content rules, the agreement must identify which party is responsible for obtaining required building consents and other approvals.

The contract should also make the practical responsibilities clear enough that you know who is handling key tasks such as council communication, inspections, subcontractor coordination and important project records.

Remember that a builder may carry out tasks for you while you still retain responsibilities as the property owner.

If you are unsure about consent or project responsibilities, revisit SeekSaver's Renovation Planning Stages Checklist NZ and current official guidance before signing.

4. Check the dates, delays and communication rules

For contracts covered by the prescribed minimum-content rules, the contract must include expected start and completion dates and explain how possible delays will be dealt with.

Read the delay section carefully.

You should understand:

• what needs to happen before the work starts;
• what can extend the completion date;
• how delay notices are given;
• whether formal notices must go to a particular email or address.

Do not assume an ordinary conversation or text message automatically satisfies a formal notice requirement in the contract.

If the delay clauses are difficult to understand or appear unusually one-sided, consider getting project-specific legal advice before signing.

5. Understand the payment schedule before you sign

For qualifying contracts, the agreement must explain the contract price or how it is calculated, the payment structure and how payments will be invoiced and made.

The important question is not simply how much you pay, but what triggers each payment.

You should be able to understand how any deposit works, what project stage or work each later payment relates to, when invoices or payment claims are due, and how approved variations affect the amount payable.

MBIE's prescribed consumer checklist advises homeowners to think carefully before agreeing to pay more than the cost of work completed and materials supplied at that point.

The Construction Contracts Act also contains statutory payment and dispute processes. If the payment wording is difficult to understand, get the clause explained rather than relying on a simplified interpretation.

SeekSaver does not recommend a standard deposit percentage or progress-payment percentage because the appropriate arrangement depends on the contract and project.

6. Check exactly how variations will work

Renovations often change once work begins.

A variation is an agreed change to the work. For contracts covered by the prescribed minimum-content rules, the contract must include a process for negotiating and agreeing variations.

The important issue is whether the contract gives you a clear way to record:

• what is changing;
• who approves the change;
• what effect it has on price;
• what effect it has on timing;
• whether any plans or approvals also need to change.

As a practical rule, do not let an important variation exist only in a verbal conversation.

Keep an agreed written record before the affected work proceeds where reasonably possible.

7. Check insurance, defects and warranties

Insurance

Do not assume that the builder automatically arranges every type of insurance needed for your renovation.

The appropriate arrangement depends on the project and the contract.

Check what insurance the contractor says it holds, what it covers, who is responsible for contract works insurance and whether you need to notify your own home insurer.

For alterations and renovations, the homeowner may need to arrange contract works insurance depending on the arrangement.

Defects and implied warranties

New Zealand law implies warranties into residential building work regardless of the project price or whether the agreement is written.

These include requirements relating to matters such as proper and competent work, reasonable care and skill, compliance requirements and suitability of materials.

There is also a 12-month defect repair period for residential building work. This is not the same as saying there is a “12-month warranty”.

If you identify a defect during that period, notify the building contractor in writing.

Also check any separate commercial guarantee or warranty being offered. It may have its own limits, conditions or exclusions, and it does not replace statutory implied warranties.

8. Understand disputes, suspension and ending the contract

A qualifying residential building contract must include a dispute-resolution procedure.

Read that section before there is a problem.

You should understand the basic process for raising a dispute, where formal notices must be sent and whether the contract refers to negotiation, mediation, adjudication or another process.

Also read clauses dealing with:

• suspension of work;
• default;
• termination;
• cancellation.

These provisions can have significant legal and financial consequences.

If you do not understand them, or the contract gives one party unusually broad rights that concern you, get project-specific legal advice before signing.

This guide does not provide a simplified rule about when you can cancel a building contract.

9. Agree what “finished” means and what documents you will receive

Make sure you understand what completion means under the contract.

For example, the physical work may appear finished while some inspections, consent records, defect work or handover documents are still outstanding.

MBIE advises homeowners to make expectations clear where they expect the contractor to remain involved until required documentation has been received.

On completion of residential building work, contractors also have statutory obligations to provide certain information, including applicable insurance information, guarantees or warranties and required maintenance information.

Depending on your renovation, your wider project file may also include council, consent, trade and product records.

Write down what you expect to receive rather than assuming everyone has the same idea of “handover”.
