People who turn up without bookings won't be permitted on the premises.
"These cats haven't seen huge crowds since the park closed and that's why numbers will be limited," operations director Janette Vallance said.
She couldn't say what the numbers would be or give other details.
Tour or school groups are requested to arrange their bookings with the park's office by telephone.
The park cannot accept bookings for unaccompanied children 15 years and under.
"By booking ahead we make sure you are not trying to see our beautiful cats over the heads of lots of other people, and, the cats don't get stressed by too much activity around them."
Vallance said there was a little more to do to get the park and the cats ready for opening day.
The park is encouraging people to register online so they'll be the first to know when ticket sales open.
The park has 20 big cats – one leopard (the only one in New Zealand), one cheetah, two tigers and 15 white, African, and Barbary lions.
It was formerly known as Zion Wildlife Gardens, and was once owned by Craig Busch, who gained global fame through the television series Lion Man which was shot there in the past.
