Proposed changes to New Zealand’s earthquake-prone building regulations could allow the reopening of Rotorua’s Blue Baths.
The government introduced proposals last month to amend New Zealand’s earthquake-prone building regulations. This would lead to 55% of buildings being taken off the current national earthquake-prone building register.
Current rules mandate that buildings performing below 34% of the New Building Standard (NBS) must either be strengthened or demolished.
Rotorua, classified as a medium-risk seismic zone, had timeframes of 10 years for initial building assessment and 25 years for strengthening. In November 2024, these deadlines were extended by four years for all notices that had not yet lapsed.
Rotorua has 80 buildings listed on the earthquake-prone building register, including notable sites like the Rotorua Museum and Blue Baths.
The museum was closed in November 2016 after the Kaikōura earthquake caused damage, and subsequent detailed seismic testing rated the building at 19% of the New Building Standard (NBS).
Meanwhile, the Blue Baths were closed in January 2021 after a detailed seismic assessment found the building had only 15% of the New Building Standard (NBS).
The new proposal would eliminate the use of the New Building Standard (NBS) as the measure for earthquake-prone buildings. Instead, buildings will be classified as earthquake-prone based on their construction materials and their proximity to public areas and neighbouring properties.
Tapsell stated that the proposed changes would have minimal effect on the cost or approach to the museum’s $73.55 million restoration project, with the historic site scheduled to reopen in 2027.
However, she said the proposal “potentially opened up the doors” of opportunity concerning the Blue Baths. Tapsell has sought a meeting with Chris Penk, the Minister for Building and Construction, to address the issues.
Tapsell emphasised the need for clear government policy requirements to ensure historic buildings like the Blue Baths can reopen in a manner that is both safe and affordable.
