A fire has gutted an abandoned psychiatric hospital near Nelson.
Five fire crews arrived to find the Ngawhatu Psychiatric Hospital "well ablaze" at about 1am on Sunday, a fire service spokesman said.
The building was empty at the time and there were no reports of injury, he said.
A team of investigators arrived at the scene in the morning.
It's the second fire at the former hospital - which operated from 1922 to 2000 - in the past year, following a blaze in November.
