Treasury is questioning the way the Crown manages its assets, suggesting the default setting of state ownership of social assets such as schools and hospitals may not be the most efficient use of government money.
Treasury this afternoon released its investment statement, a snapshot of the Crown's assets and liabilities.
The Crown's total assets of $244 billion and liabilities of $174 billion as at June 30 last year had been previously reported in the Crown Financial Statements.
The statement said the Government's balance sheet would continue to grow along with the wider economy.
The Crown's financial assets such as ACC and the Super Fund would grow particularly quickly and increase as a proportion of total assets due to the aging population.
