Two more entities established by Allan Hubbard are likely to be put into statutory management, Prime Minister John Key says.
In June, Mr Hubbard's company Aorangi Securities, seven charitable trusts, Mr Hubbard and his wife, Jean, were put into statutory management.
The Temple Bar Family Trust and Barns Charitable Trust were last week put into statutory management on recommendation from the Securities Commission.
The commission made the recommendation after receiving a report from the statutory managers of Aorangi Securities.
Mr Key today said besides the two trusts put into statutory management last week, a couple of others were being looked at. "The two we left out we thought we could leave out, but in hindsight, for a variety of reasons, we don't think we can now."
Managers were still looking into whether there any more entities under Mr Hubbard's control, but Mr Hubbard had previously been questioned about related entities "and we haven't necessarily got a straight answer", Mr Key said.
Mr Hubbard was also the founder, and chairman for life, of South Canterbury Finance (SCF) which went into receivership last month with taxpayers paying out $1.6 billion to investors under the retail deposit guarantee scheme.
Labour has been putting pressure on the Government to be fully transparent about its handling of SCF, and has called for a commission of inquiry.
Hubbard supporters have also called for a public inquiry, but Mr Key said he didn't see a need for that.
"There is no magic here. On the one side, quite simply, South Canterbury Finance made loans to people who couldn't repay them. The vast bulk of those risky loans took place between 2007 and 2008 - before the guarantee was actually put in place - and they formed a majority of the bad bank."
The Government had simply honoured its obligations under the guarantee because it was legally and morally obliged to, he said.
"In due course it's the view of (Finance Minister Bill English) to release as much of that information and the paper trail that was put together through the whole of the South Canterbury Finance affair into the public domain - notwithstanding any that may have to be retained on the basis of confidentiality."
