The building that houses the Reserve Bank of New Zealand in central Wellington is closed until further notice after the discovery of asbestos on one level.
The bank's essential operations, such as financial markets, were being done from the bank's Auckland premises and were not affected, the bank said in a statement.
A small trace of asbestos was discovered on level 1 yesterday.
"We undertook an air test on level 1 and have since learned that this is clear, and appropriate remedial action has been taken on this level," Reserve Bank Governor Adrian Orr said.
