"It is more like a discussion," she said but would not comment further.
The troubled Whangarei wildlife park reopened three months ago after a bitter ownership dispute, numerous court battles and the death of one of the park's animal handlers who was mauled to death by a tiger in May 2009, in front of horrified visitors.
Mr Busch is back running the park, now known as Zion Wildlife Kingdom and under new ownership.
The Northern Advocate reported in April that Mrs Busch had filed a statement of claim in the High Court, alleging the park's receivers PriceWaterhouseCoopers had failed to publicly advertise the sale of the park through an open tender.
Mrs Busch, her daughter Megan, Country Developments and Wildlife Pictures have sought damages and costs against Mr Busch, PriceWaterhouseCoopers, Ministry of Agriculture and Forestry, Kingdom of Zion and its new owners.
Receiver Colin McCloy said at the time that the claim was without foundation.
