The Government had a smaller than expected first-half operating deficit after Treaty of Waitangi settlement costs didn't eventuate in the period, and tax revenue was in line with forecasts.
The operating balance before gains and losses (OBEGAL) was a deficit of $3.19 billion in the six months to December 31, 4.7 percent smaller than expected in the December half-year economic and fiscal update, according to the Crown's latest accounts
Core tax revenue of $27.34 billion was just 0.1 percent off the forecast, while core expenses of $34.14 billion was 0.8 percent below forecast.
The main reason behind the lower expense line was $186 million of costs on Treaty settlements being delayed by complex negotiations, the Treasury said.
The Government is trying to get its books back in the black in the 2014/15 financial year after taking serious hits from the global financial crisis and Christchurch earthquakes.
In the update just before Christmas, Treasury forecast an OBEGAL surplus of just $66 million in the 2014/15 financial year, down from the $197 million buffer flagged in the May budget.
The Crown posted an operating surplus of $1.71 billion in the six month period, beating the deficit of $541 million forecast, after the New Zealand Superannuation Fund and Accident Compensation Corporation's investment portfolio posted better than expected investment gains, and as the accident insurer reported an actuarial gain.
The investment gains were $1.29 billion ahead of expectations, while ACC's actuarial gain was $780 million.
The accounts show the company tax accrued in the period was 7.1 percent below forecast at $3.13 billion, though non-resident withholding tax of $190 million was 17 percent higher.
Personal income tax accrued was one percent ahead of forecast at $11 billion, while other persons tax was 5.2 percent above forecast at $2.3 billion. Goods and Services Tax after refunds was 1.4 percent short of expectations at $7.07 billion.
The Government's net debt of $59.1 billion, or 28.4 percent of gross domestic product, was two percent below the half-year forecast.
