Former Hanover Finance head Mark Hotchin is fighting for a $7000-a-week allowance to sustain his lifestyle on Australia's Gold Coast.
The Securities Commission regulatory agency gave the Hanover co-founder a $1000-a-week allowance after freezing his New Zealand assets.
It is understood Mr Hotchin has sought to increase that limit to between $6000 and $7000, to pay the rent, living costs, for a hire car and private school fees for three children.
A High Court legal meeting will be held today.
Mr Hotchin's lawyer, Bruce Stewart QC, last week said his client was supporting seven people and could not afford to live on $1000.
As well as negotiating his allowance, Mr Hotchin's legal team will today argue for access to a report by forensic accountant David Crichton, which served as the grounds for the court order against him.
The commission has so far refused to allow Mr Hotchin or his lawyers to see the document or discuss its contents.
The Securities Commission used unprecedented powers to freeze Mr Hotchin's assets in a High Court order this month in case any Hanover investors want to bring civil claims against the company and its directors.
The High Court order - not released to the media - could cover his bank accounts, sections at Jacks Point near Queenstown, an incomplete $30 million mansion in Auckland, a $13.5 million farm and holiday home on Waiheke Island, a 69ha Coromandel farm, and a prize racehorse.
Mr Hotchin said in a statement he would appeal the commission's freezing orders.
He has not given any indication when or if he will return to New Zealand.
Thousands of investors had half a billion dollars in Hanover deposits frozen when the company collapsed in July 2008.
In the years before the crash, Mr Hotchin and fellow owner Eric Watson took $91 million in dividends.
After a scheme to pay back investors over five years failed, investors voted to swap their deposits for shares in Allied Farmers, but the shares have since plummeted.
The Securities Commission is deciding whether to lay charges against the former directors of Hanover Finance, United Finance and Hanover Capital.
The investigation is nearly complete.
Several parties have indicated that they will take civil action against the company.
Tim Rainey, a lawyer representing 3000 Hanover investors, expects to have a case ready by February.
