Expenditure was in line with forecast at $29.16 billion, with higher than expected defence of $72 million offset by reduced costs across a range of departments.
The Crown's core residual cash deficit was $4.01 billion in the five-month period, a bigger shortfall than the $3.79 billion forecast, and is forecast to return to surplus in 2017, after which the government plans to start reducing debt.
The period includes the government's $365 million sell down of its Air New Zealand holding, on which it recognised a gain of $52 million.
The government's net debt at $59.59 billion, or 27.6 per cent of gross domestic product, was slightly lower than forecast, and gross debt of $83.21 billion, or 38.5 per cent of GDP, was in line with expectations.
The operating balance, which includes movements in its investment portfolios and actuarial adjustments, was a surplus of $2.26 billion, $1.6 billion ahead of the December forecast due to net gains from the New Zealand Superannuation Fund. That compares to a surplus of $706 million a year earlier.
