The Treasury forecast an Obegal deficit of $572 million in the year ending June 30, 2015, turning to a surplus of $565 million the following year.
The bigger than expected tax-take came from other individual taxes coming in 6.1 per cent ahead of forecast, with January the second provisional tax payment date for the March balance date, which also helped the company tax take being 3.2 per cent above expectations.
The growing momentum in New Zealand's labour market helped lift income tax, which was 1 per cent ahead of forecast, though GST remained below expectations.
Crown expenses were $249 million below forecast with smaller costs spread across a number of departments, with the biggest variances coming from fewer applications for grants and subsidies than expected, and delays finalising Treaty of Waitangi settlements.
The Crown's operating balance, which includes fair value adjustments in its investment portfolio and actuarial movements, was a deficit of $2.28 billion, smaller than the $3 billion forecast in the December half-year economic and fiscal update.
The government posted a surplus of $3.37 billion a year earlier, when its investment portfolios were riding gains in global financial markets.
The deficit has been running wider than expected in prior months due to widening actuarial losses due to the prospect of low interest rates running longer than anticipated.
The liability for Accident Compensation Corp was $34.92 billion, some $4.5 billion more than expected, while Earthquake Commission property damage liability was $370 million than forecast at $3.66 billion.
The Government's net debt was $61.78 billion, or 26.1 per cent of gross domestic product, as at January 31, $1.17 billion below forecast, while gross debt of $87.23 billion, or 36.8 per cent of GDP, was $3.59 billion more than expectations.
The Crown's residual cash deficit was $763 million less than expected at $2.4 billion, and almost half the $4.11 billion in the same period a year earlier, due to the tax take coming in ahead of expectations.
