The Government says it does not expect the receivership of a property lender, covered by the Crown extended retail deposit guarantee, to have a significant impact on its books.
Equitable Group went into receivership on Friday, triggering a payment of $178 million.
Labour says the Government has not put enough money aside to provide for company failures.
But a spokesperson for Finance Minister Bill English says provisions have already been made for failures, with about $850 million set aside in Crown accounts.
He says the Crown's net costs, as a result of the receiverships, are not expected to rise above this amount.
However, Labour says this provision is not sufficient to cover recent company failures.
Finance spokesperson David Cunliffe says the Government's calculations were wrong and the Budget will be more than used up by South Canterbury Finance and Equitable Group.
He says this is yet more bad news for New Zealand.
