The Ministry of Business, Innovation and Employment (MBIE) announced updates to acceptable solutions and verification methods for plumbing, drainage, and fire protection within the Building Code. These amendments aim to improve the safety and well-being of New Zealanders in their homes, according to Dr. Dave Gittings, Manager of Building Performance and Engineering, according to a media release issued on Thursday.
The plumbing updates involve the adoption of the latest version of the AS/NZS 3500 plumbing and drainage standards, which include New Zealand-specific requirements. These changes focus on increasing protection for vulnerable individuals, such as children and the elderly, from hot water scalding and safeguarding drinking water from backflow contamination.
In terms of fire protection, the latest industry standards for fire sprinkler, fire alarm, and smoke control systems will be cited, including interconnected smoke alarms as the minimum fire safety system in new homes. Aligning with other countries' requirements, these updates aim to enhance the safety of New Zealand communities.
Portions of the fire proposal related to protecting townhouses and low-rise multi-unit dwellings from fire spread have been withdrawn due to mixed feedback. MBIE plans to conduct further engagement and consideration on residential fire protection.
The revised acceptable solutions and verification methods documents will be published in November 2023, allowing a 12-month transition period before the previous versions are phased out.
