Technical Manual

The Technical Manual covers the Homestar process and contains detailed information on how to meet the requirements for each credit.

Homestar v4 technical manual

Homestar v4 is the latest version of Homestar, effective from 25 July 2017.

Version 5 is currently under development for release in 2021.


The Homestar Checklists are a simple way to achieve a 6 or 7 Homestar based on the credits that people most often target for Homestar. If targeting a higher rating, we recommend downloading the Technical Manual above.

Registration Form

The project owner must complete the Registration Form, confirm that they have read and agree to the Homestar Terms and Conditions, and email to to start the registration process. A project can be registered before engaging a Homestar Assessor, but we recommend discussing the project with an Assessor first to better understand the assessment process. Refer to process and fees page for an estimate of admin and audit fees paid to NZGBC.

Homestar Registration Form multi unit (PDF)

Note, if you are intending to submit this multi-unit development for audit in stages, please register each stage as a separate Homestar project. If you register your entire development as one project, and later find you need to submit it in stages, we will split the registration and invoice you again for the fee difference. This can add delays to the audit and certification process, so please avoid this where possible.

We require multi-unit developments to submit a Typology Breakdown at registration. Your Homestar Assessor should prepare this for you. This should be a site plan showing each dwelling included in this rating, referenced to its typology, AND an explanation of how the Typologies were defined as per the definition in the Technical Manual. Please attach this to your email when you submit your registration form.

Resources for Assessors


The NZGBC may award innovation points as part of a Homestar rating. These recognise initiatives that don’t currently fit in to the main framework of these tools but that we believe are important to encourage. They cover environmental, social and economic sustainability initiatives. 

The NZGBC has published set Innovation Challenges for Homestar and Green Star that any project may target. Or, Homestar Assessors may suggest new innovations to the NZGBC for approval which are reviewed by independent experts. Please refer to the Innovations section of the Technical Manual to understand how these fit into the framework of the Homestar tool.

Products and Materials

Homestar assess the whole dwelling, not dwelling components. Products and materials can contribute to a Homestar rating, but we rely on third-party certifications and eco-labels rather than endorsing specific products. These third-parties test and carry out environmental assessments of products and materials, independent from manufacturers, suppliers and the NZGBC.

Products and materials relate to Homestar in two different ways:

  1. In the Materials category, points are awarded for healthy & sustainable materials. 
  2. Product may contribute to the overall sustainable performance of the building. For example, low-flow water fittings are recognised in the Water Use credit.

Please refer to the Homestar Technical Manual for more details.

If you’re a manufacturer or supplier of a product or material that is eligible for points under Homestar, get in touch with for advice on marketing your product and communicating its benefits through NZGBC membership.

If your product has an eco-label that is not currently recognised by the NZGBC, please refer to the Product Certification information from the Green Building Council of Australia. This provides further details on how the product certification scheme providing the eco-label can apply for assessment against the GBCA Assessment Framework. A submission may be made by the product certification scheme or by another party on their behalf, provided the appropriate documentation can be supplied.
