The Labour Party is calling for a commission of inquiry into the Government's handling of the collapse of South Canterbury Finance.
Finance spokesperson David Cunliffe says there are many questions about the Government's intervention that only an independent inquiry can answer.
Mr Cunliffe says a select committee inquiry would not be good enough.
He says the Government could have adopted other options to deal with South Canterbury Finance - options that would have reduced the cost to taxpayers.
But Finance Minister Bill English rejected calls for a commission of inquiry, saying an inquiry is unnecessary, although government documents will be made public.
