Halfway through its financial year the Government's budget deficit is $4.1 billion, $1.9 billion less than in the same period the year before.
But most of the difference is due to the impact of the Canterbury earthquakes on the Earthquake Commission. Tax revenue grew faster than government spending between the two periods.
In the six months to December 31, the tax take was $26.4 billion, 5.5 per cent higher than in the same period in 2010, while core Crown expenses rose 3.5 per cent to $34.1 billion.
Nearly half the tax increase was in corporate tax. Most of the rest was an increase in the GST tax following the higher rate which came into effect in October 2010.
Among the big-ticket items on the spending side, welfare (which includes NZ Superannuation) was 2.2 per cent higher at $11 billion, health spending 2.8 per cent higher at $7 billion and education 2.1 per cent higher at $5.8 billion. In addition, higher levels of debt saw the Government's interest bill rise $400 million or 28 per cent.
