In May 2009 - when the park was known as Zion Wildlife Park and run by Zion Wildlife Gardens, owned by Patricia Busch - big-cat handler Dalubuhle Ncube, also known as Clifford Dalu MnCube, or Dalu, was mauled to death by a male tiger named Abu after he and another handler had entered its enclosure to clean it.
In December 2011, Zion Wildlife Gardens was ordered to pay reparations of $60,000 to Dalu's partner after pleading guilty to one charge under Section 6 of the Health and Safety in Employment Act 1992.
Mr Weekes said Bolton Equities - which has Murray and Robyn Bolton, from Remuera; Edward Davie, from Australia; Kenneth MacDonald, from Tauranga; and Phillip Wells, from Auckland; listed as directors - was a private investment company that saw huge potential for the big-cat park.
"The aim is to get it up to the required (MPI) standards and turn the park into a truly world-class big-cat breeding facility that will be open to the public. (Bolton Equities) sees this as a fantastic facility and want to make sure the public have a wonderful place that they can go and visit to see some amazing big cats," he said.
Mr Weekes said the company did not see the park as a major money maker and were investing in it as a "labour of love because they love big cats".
"Craig Busch isn't involved in the new venture - he has his own park in South Africa - but he's welcome to come to the park any time. He's worked very hard to get the place up and running," he said.
Mr Weekes said the park had 34 big cats - lions, tigers (including white tigers), cheetahs and a black leopard - and some of them might go to Mr Busch's park in South Africa while the Kamo park might take some big cats from the South African park.
"People need to realise that this facility is pretty unique anywhere in the world, in terms of the number of big cats and what we are trying to do," he said.
The company hoped to re-open the park as soon as it had been given the all-clear by MPI so that it could finally become the world-class tourist facility it had always promised to be.
