Remedial work at Whangarei's Kamo Wildlife Sanctuary is still being done and the park will be closed at least until the end of February.
Bolton Equities, which is based in Remuera, Auckland, but has land holdings in Northland, bought the park from previous owners Earth Crest and the place is being upgraded to meet new rules around animal enclosures.
The park was also formerly owned by TV's the Lion Man, Craig Busch.
The Ministry for Primary Industries (MPI) ordered the park closed to the public between July 1 and July 31 while the animal enclosures were upgraded to meet new standards. MPI then extended the closure until August 31 but the upgrading has still not completed.
Martin Weekes, a director of Bolton Equities, said the company was working through a list of remedial work, including building extra enclosures, with at least four to six weeks of work still to be completed.
