Patricia Busch's licence as operator of Zion Wildlife Gardens is under threat after revelations an undisclosed party has applied for her job.
The Ministry of Agriculture and Forestry yesterday confirmed an application had been received for operator's status which was being considered.
It refused to identify the interested party or when the application was lodged.
The news follows an announcement that the park will officially re-open on Easter weekend, with Lion Man Craig Busch on hand to welcome visitors and run some tours.
The ministry said it had no involvement in the park's public reopening or its business operations.
