Huka Lodge owner Alex van Heeren will get the chance to explain the extent to which he has any control over two entities in the land-locked microstate of Liechtenstein where he transferred all of his assets.
This follows van Heeren's former business partner arguing that the Dutch businessman should have his financial affairs probed before a judge at the High Court in Auckland.
The bid by South African steel trader Michael Kidd was another turn in his 19-year-long fight with van Heeren over the breakup of their business partnership.
Kidd claimed he got less than US$5 million ($7.5 million) when they severed ties in 1991, while van Heeren allegedly held on to assets worth at least US$47.5 million - including Huka Lodge, Dolphin Island retreat in Fiji and 32kg of gold.
Earlier this year, Justice John Fogarty ordered van Heeren to pay US$25 million to the High Court in Kidd's favour as part of the dispute.
