6. Legal Framework

Our use of cookies is governed by:

New Zealand does not have a separate cookie consent law equivalent to the EU ePrivacy Directive. However, the Privacy Act 2020 requires transparency and fair collection practices. We obtain your consent for non-essential cookies through our cookie banner as a matter of best practice and GDPR compliance.
