On whether she would like to see her son take back the park, she said: "Absolutely. It's his idea and he was the founder. I still love him of course."
Mrs Busch said she last spoke to her son on July 2 when he called her from Auckland.
She said that on Wednesday, the receivers discussed the operation of the park - which is in liquidation - and its records.
She said the animals were well fed and looked after with funds from gate takings as well as donations.
The park would be open to the public while the receivers carried out their work through the liquidation process, Mrs Busch said.
Receiver Colin McCloy, of PricewaterhouseCoopers, arrived at the park shortly after 11am and headed to the main office before he was led through the park to meet Mrs Busch.
He refused to speak to waiting reporters, saying he would be busy in meetings.
PwC later issued a news release and quoted him as saying: "We have gained access to the park and have received full co-operation from Patricia Busch. We're talking with Patricia Busch and now exploring a way forward.
"I want to reiterate we are committed to doing the best we can for the welfare of the wildlife and ensure we continue to maintain the current welfare standards of the animals at Zion Wildlife Gardens."
On Tuesday, the High Court ordered Mrs Busch to open the gate to the receivers and to make available all books, documents and information they required.
It took the receivers two weeks and a second court order to get into the park after it went into receivership last month, because Mrs Busch refused to let them in.
Craig Busch could not be contacted to respond to his mother's comment.
