Regulations & Consent For Solar Power in NZ
Grid connected solar power systems must comply to local lines companies, along with NZ electrical standards and local council regulations. The council will look at certain installation and electrical safety requirements. Solar power systems can overload power lines; it is lines companies that make sure this doesn't happen.
Do solar power systems in NZ need council consent?
Some council’s in New Zealand require consent applications.
Building or resource consent is a bit of a grey area as the Building Act of 2004 exempts energy work from requiring a building consent. Some New Zealand solar installation companies suggest that there is no need for any one in New Zealand to get council consent. Be cautious, you may wish to call your local council or ask your installer to find out the councils exact requirements.
Some council’s do not differentiate between solar power and solar hot water systems. You might be forced to fill out an application for solar hot water consent… it happens!
Heritage-listed buildings may require resource consent and strict zones may also require consent.

All lines companies require consents. If you are going to be exporting solar power to their power lines, then they need to know!
They want to make sure that the technical specifications of your system meets their prerequisites.
Lines companies on occasion reject grid connection requests based on the size of the system. Often, this will be resolved by installing a smaller system or installing a zero export device.
