ACT leader David Seymour wants Auckland exempted from the rules around earthquake-prone buildings.
The Epsom MP says the city has an extremely low risk of a severe earthquake.
"According to GNS Science, the probability of a severe earthquake in Auckland is one in 110,000 years," he said.
"That's 7333 percent less likely than in Wellington."
The building rules were developed following the 2011 Christchurch earthquakes.
A bill that changes the way earthquake-prone buildings are managed is going through parliament, and Mr Seymour says he'll vote against it unless Auckland is exempted.
"It will impose enormous costs on private property owners forced to undertake expensive engineering assessments to prove they are compliant," he said.
