From 1 January 2021, NABERSNZ standards will be compulsory for all Government agencies who occupy single-tenant, co-tenanted, or co-located government offices.

Minimum standards:

• Existing buildings: Agencies entering a new lease, or renewing an existing lease should target a rating above 5 stars, and achieve a minimum of 4 stars.
• New buildings: Agencies planning a new build project need to achieve a minimum of 5 stars.
• Co-assess ratings: Co-assess is a process that enables tenancy ratings to be conducted as part of a whole building or base building rating. For example, a collection of tenancy assessments undertaken for multiple agencies in a co-tenancy building.

Assessments will be valid for 12 months. If the target rating has been met, a re-rating will be required every three years. If the target rating has not been met, an agency must implement a work programme within 12 months to achieve the target rating and re-rate the building annually until the minimum star rating is achieved.

Agencies will be required to disclose their NABERSNZ assessment via the Government Property Portal (GPP). This rating will be publicly available on the NABERSNZ website.
