Phil Hope, the senior guardian of Oamaru's famous Victorian precinct, has grave fears for the North Otago town if the Government pushes ahead with a proposed 15-year deadline to strengthen buildings.
The Oamaru Whitestone Civic Trust, which Mr Hope chairs, supports strengthening unreinforced masonry buildings but believes a more reasonable timeframe would be 30 or 35 years.
The exception would be low-lying fruit, such as parapets and chimneys, which were the cause of several deaths and multiple injuries in the Christchurch earthquakes.
Oamaru is believed to have the largest collection of Category 1 and Category 2 listed heritage buildings of any provincial town in New Zealand.
The town's Victorian precinct, comprising buildings constructed of local sandstone between the mid 1860s and mid 1880s, is one of New Zealand's most impressive streetscapes and a major tourist attraction.
