Discovering that earthmoving work on your property hasn't been done to a satisfactory standard is frustrating — and it can have real consequences for drainage, structural stability, and your land's long-term health. The good news is that New Zealand homeowners have several clear pathways to raise a formal complaint and seek a remedy, whether the issue is poor grading, damaged services, erosion problems, or work that doesn't match what was agreed.
Step 1: Document Everything First
Before you contact anyone, gather your evidence. Take dated photographs and video of the problem areas, note any visible issues such as uneven ground, pooling water, collapsed batters, or damage to fences and services, and write down a clear timeline of events. Dig out your written contract or quote, any plans or specifications, and any correspondence (texts, emails) with the earthmover. Good documentation is the foundation of any successful complaint.
Step 2: Raise the Issue Directly With the Contractor
In most cases, the first step is to contact the earthmover directly — ideally in writing (email is fine) so there's a record. Describe the problem clearly, refer to what was agreed in the contract or quote, and state what remedy you're seeking (e.g., rework, a partial refund, or repair of damage). Give them a reasonable timeframe to respond, typically 5–10 working days.
Many disputes are resolved at this stage. Reputable earthmoving contractors want to protect their reputation and will often return to fix genuine defects.
Step 3: Check Whether a Building Consent Was Required
Some earthmoving work — particularly significant cut and fill, retaining walls over certain heights, or work near boundaries — may require a building consent under the New Zealand Building Code. Check with your local council to find out whether the work needed consent and whether it was obtained. If consented work has been done poorly, the council's building control team may be able to inspect and issue a notice to fix.
For guidance on what requires consent versus what falls under Schedule 1 exemptions, visit MBIE Building Performance — but always confirm with your local council, as requirements can vary.
Step 4: Contact Your Local Council
If the earthmoving work has caused environmental harm — such as sediment runoff into a waterway, damage to stormwater infrastructure, or breaches of resource consent conditions — your local or regional council's environmental or compliance team can investigate. This is separate from the building consent process and relates to the Resource Management Act (RMA).
Councils take sediment and erosion control seriously, and a contractor who has breached resource consent conditions can face enforcement action.
Step 5: Escalate to the Disputes Tribunal
If direct negotiation fails and the amount in dispute is under the current Disputes Tribunal monetary limit (or a higher amount by agreement), you can apply to the Disputes Tribunal — New Zealand's small claims court. It's relatively low-cost, doesn't require a lawyer, and decisions are legally binding. You'll need your documentation, photos, and ideally an independent assessment of the defective work.
For disputes over $30,000, you may need to consider the District Court or engage a lawyer. Consumer NZ has useful guidance on resolving disputes with tradespeople.
Step 6: Seek an Independent Assessment
For significant disputes, it's worth getting an independent geotechnical engineer or civil engineer to assess the work and provide a written report. This gives you an objective, expert opinion on whether the work met acceptable standards and what remediation is needed. Their report can be used as evidence in the Disputes Tribunal or court.
Step 7: Check for Industry Membership
Some earthmoving contractors are members of industry bodies such as Civil Contractors New Zealand (CCNZ). If your contractor is a member, you may be able to raise a complaint through the association's complaints process. Check the contractor's website or ask them directly.
When to Call a Professional
If earthmoving work has affected the structural stability of your land, damaged retaining walls, or caused drainage problems that are worsening, don't wait — get a qualified geotechnical or civil engineer to assess the situation promptly. Ongoing erosion or slope instability can become a safety issue.
For work involving underground services (gas, water, electricity), contact the relevant utility provider immediately if you suspect damage. Gas and electrical work near damaged services must be assessed by licensed professionals — see WorkSafe NZ for safety guidance.
