Hawke's Bay's "high-risk" earthquake status means it has missed out on a relaxation of costly seismic strengthening rules, which has been welcomed in other parts of the country.
Hastings Mayor Lawrence Yule said that, with existing deadlines to strengthen the region's earthquake-prone buildings set to remain, he would continue lobbying for central government funding to help fix affected historic buildings such as the Hawke's Bay Opera House.
The Government has said the changes to how quickly earthquake-prone buildings will need to be assessed and strengthened would reduce the number that would require assessment nationwide from an estimated 500,000 to 30,000, and bring down the total estimated cost from $1.36 billion to $777 million.
But existing rules - requiring buildings that could be a risk to be assessed within five years, with any strengthening carried out within 15 years - are not changing in Hawke's Bay and other "high-risk" earthquake regions, including Gisborne, Wellington and Canterbury.
Mr Yule said in his other role as president of Local Government New Zealand he had been lobbying the Government over the need for financial assistance to preserve at-risk historic buildings, particularly in the high-risk regions. "That will be something we continue to push, I'm working hard on it. If it were to be recognised, potentially the Opera House could be part of that mix."
