A member of the public scaled a crane on a building site in downtown Auckland.
A police spokeswoman said they received reports a man had climbed the crane at a site between Customs St and Quay St, near the waterfront.
A police spokeswoman said the man had since climbed down safely and was speaking with police.
It was not clear why he had climbed the crane, she said.
Police, Fire and Emergency and St John were at the scene.
A witness said the man had made it to the top of the crane, before being talked down by police officers.
A video supplied to the Herald showed the man had made it past the cabin and out onto the boom arm of the crane.
A crowd had gathered around the site.
She was stabbed repeatedly in the face, upper torso and abdomen by a man in her home.
