Earthworks are a necessary part of preparing land for residential development, but if the right practices aren’t used, soil can be lost to water bodies. Having a clear plan for erosion and sediment control, getting the right consents and meeting relevant conditions protects you, your property, your neighbours and the environment.
To find out whether you need a consent, contact our Consents team before getting your project underway.
We are available to guide you through this process and provide tips on how to make it a smooth experience.

Residential development: Means the preparation of land for, and construction of, development infrastructure and buildings (including additions and alterations) for residential activities, and includes retirement villages. It excludes camping grounds, motor parks, hotels, motels, backpackers’ accommodation, bunkhouses, lodges and timeshares. The terms development infrastructure, residential activity, and retirement village are defined in the National Planning Standards.
Earthworks: The alteration or disturbance of land, including by moving, removing, placing, blading, cutting, contouring, filling or excavation of earth (or any matter constituting the land including soil, clay, sand and rock). This excludes gardening, cultivation, and disturbance of land for the installation of fence posts.
Landholding: For land subject to the Land Transfer Act 1952, land in: (i) A single certificate of title; or (ii) Two or more adjoining certificates of title, with a common occupier. For land not subject to the Land Transfer Act 1952, all contiguous land last acquired under one instrument of conveyance and occupied by a common occupier.
This Guide provides context to ORC residential earthworks provisions, consent information and on-going consent compliance requirements. This includes content required for any Environmental Management Plans (EMPs) and Erosion and Sediment Control Plans (ESCPs) which are necessary for the majority of consents granted by the ORC.
Please read this Guide in conjunction with Auckland Council’s Erosion and Sediment Control Guide for Land Disturbing Activities in the Auckland Region Guidelines Document 2016/005 (GD05) and the applicable resource consent if and when granted.
This form is an editable pdf that can be used to report many types of incidents to the ORC via the ORC Compliance Officer assigned to your site, compliance@orc.govt.nz and the Pollution Hotline. It is a condition requirement of residential earthworks consents. The incident may need to be reported immediately to ORC’s Pollution Hotline.
Please consider using this template if your team doesn’t already have a Site Environmental Induction form.
If you have a SRP and chemical dosing system on your site you will be required to have a Suitably Qualified and Experienced Person (SQEP) certify the SRP and chemical dosing system.
Please use this form and submit to compliance@orc.govt.nz and the ORC Compliance Officer assigned to your site.
The provisions have been developed to manage the discharge of sediment from earthworks resulting in adverse effects on water quality. Rules 14.5.1.1 and 14.5.2.1 set out the specific requirements for earthworks. You will need a resource consent if you can’t meet all the below criteria:
If you cannot meet one or more of these criteria, you will need both a regional land use consent under section 9(2) RMA and a discharge consent under s15 RMA.
Note: Look out for discharges into District or City Council networks (such as stormwater and/ or sewer lines). You may require affected party approval from them.
The best measures to manage the effects of earthworks depend on the type and scale of the activity and site characteristics that affect the risk associated with an activity. Factors influencing the amount of soil loss from earthworks sites are:
Types of mitigation measures include:
We strongly encourage the submission of management plans (such as erosion and sediment control plans) as part of an application so we can ensure that you are using the best options to control sediment run-off.
Depending on its nature and location an application involving earthworks for residential development may require other resource consents, for example:
Note: You may also need bylaw approval from ORC for this.
