The email, from the school’s board chair and principal, said they hoped the school would be able to reopen on Tuesday.
“We are so sorry to have to close on such short notice, as we appreciate the pressure that this puts on many of you.”
A spokesperson for the Wellington City Council said the slip occurred over the weekend and a private contractor is currently working to clear it.
“They will reconnect the lateral when the slip is clear. They expect to be done today.”
Last year the Terrace was hit by a massive slip caused by heavy rain which sent a large swathe of the hill collapsing on to the road. Around 600 cubic metres of soil fell, forcing 12 households to evacuate, and two were unable to return.
