Auckland Council says the site of the demolished Palace Hotel is unsafe and has resumed clearing it, despite objections from the property's co-owner.
The 124-year-old building was knocked down last month due to fears it would collapse after large cracks formed while it was being renovated.
The Wellington-based Chow Group planned to turn the 124-year-old building into a brothel.
Contractors are busy moving the debris, flouting trespass orders from the property's co-owner Michael Chow.
The Auckland Council says it has ordered work to start again for safety reasons.
It says that, among other things, the land holding up footpaths around the site is cracking and there is a lean-to which is still standing and is dangerous.
It had tried to clear the site about a week ago but was stopped by Mr Chow, who used cars to blockade contractors trying to clear the rubble.
