A large Auckland college has been evacuated due to a "threat to the school".
However, police have investigated and told staff the grounds are safe.
Western Springs College students were released at 1.30pm Wednesday, the school said on its website.
"Western Springs College is currently following its evacuation procedures. This is as a result of threat to the school."
The college was liaising with police, who were on site, the notice said.
Officers had advised that students should be released "for their safety" while police carried out their investigation, the school said.
A Western Springs teacher said he had been told it was a bomb threat.
A police spokesperson said the school had been evacuated as a precaution "following second-hand information of a threat towards the school".
The threat was received about 12.50pm.
"Police have since made enquiries at the school and, at this stage, nothing untoward has been located and the reports have not been substantiated."
A follow-up post on the school's website said police had supported the school throughout the incident "and have now advised that it is safe".
The school would remain closed for the rest of Wednesday, the post said.
