Guidelines for engineering approval applications

Professional advice for engineering approval

The engineering approval process applies to infrastructure works that are either:

  • already publicly owned
  • will be managed by us for the life of the asset.

To ensure the design and construction of the assets is fit for purpose, key phases of the process need to be undertaken by qualified and experienced professionals. This ensures Auckland ratepayers are not burdened with unreasonably high future maintenance and renewal costs.

To design and supervise the work, you will need a NZ Chartered Professional Engineer or registered professional surveyor with experience in land development and infrastructure.

For more specific advice, see the Code of Practice for Land Development and Subdivision.

For projects involving water and wastewater, it is important to review Watercare's Compliance Statement Policies:
