Sentencing has been cancelled for Zion Wildlife Park for failing to protect keeper Dalu Mncube.
He was killed by a tiger in 2009.
The Whangarei District Court has agreed today to cancel Friday's scheduled sentencing after Park director Patricia Busch applied through her lawyer this week to vacate the guilty pleas she made in June.
The court has given Zion time to explain its change of mind despite objections from prosecutors.
The Department of Labour says now the company is in receivership Ms Busch no longer has a right to represent it.
