Certified Energy

The New Zealand Energy Certificate System (NZECS) is administered and developed by Certified Energy. Certified Energy is a commercial, for-purpose entity, registered as a company in New Zealand.

Our vision: Alignment between our nations values & ambitions & the way we produce energy.



The method and approach of the NZECS should be open and available for critical review and comment, in order to promote trust in the system and identify areas of weakness.



Building on transparency, all suggestions for evolution and improvement of the NZECS should be received equally; and the evolution of the system determined via an unbiased, evidence-based decision-making process.



The system should be run in the appropriate manner as to provide the best outcome, with the most efficient use of resources. The NZECS should aim to always maintain the right balance between a service that is great quality and great value-for-money.



The NZECS should seek to provide greatest value for its immediate stakeholders. Alignment with international systems is important to maximise future opportunities for system users and ensure robustness, but should not over-ride domestic requirements where a better outcome can be achieved for New Zealand stakeholders.

Continuous evolution

To promote transparency and visibility, the NZECS will continue to evolve to assist energy consumers and generators in this country to understand and access information about their energy consumption, and to support renewable generation.

The New Zealand Energy Certificate System is operated in accordance with a number of guiding principles

Board of Advisors

The establishment, operation and development of the system is guided by a number of senior New Zealand professionals.
