Ngā aratohu mō ngā tono whakaaetanga pūkaha Guidelines for engineering approval applications

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, read the Code of Practice for Land Development and Subdivision documents. These are available on the Auckland Design Manual website. Select 'Regulations' from the tab options and then navigate to the '8. Infrastructure Code of Practice' dropdown menu. You can download the relevant code of practice document underneath each chapter.

For projects involving water and wastewater, it is important to review Watercare's compliance policies and standards. For more information, visit:

• Water network standards
• Compliance statement policy for producing water and wastewater infrastructure (PDF. 551KB)
