On the revenue side the PAYE tax take was up $744 million or 4.7 per cent on the same period last year. Other individuals' tax, which includes investment income, was 18 per cent or $575 million higher driven by recent strength in equity markets, the Treasury suggests.
But the company tax take was 1.5 per cent or $76 million lower than in the same period last year. GST, by contrast, was up by $504 million or 4.3 per cent.
Compared with Treasury's forecasts last December, tax revenue at $41.9 billion is 1.3 per cent ahead of expectations while core Crown spending at $52.2 billion is just 0.1 per cent above forecast.
The operating balance excluding gains and losses (Obegal) at $5 billion is 5.2 per ahead of forecast.
And the operating balance, including net gains, was in surplus by $2.5 billion, around $4.5 billion above the forecast deficit, largely because of significant net investment gains made by the New Zealand Superannuation Fund and ACC ($1.7 billion and $0.7 billion above forecast, respectively), the Treasury said.
The cash deficit - when the retained profits of the State-owned enterprises and Crown entities, the New Zealand Superannuation Fund's surplus and other non-cash items are backed out - is $5.6 billion, or $7.6 billion when capital spending, like the building of new schools, and loans to students and district health boards are included.
The Government's net debt at $58.5 billion is equivalent to 27.9 per cent of gross domestic product and $1.4 billion higher than a year ago.
Finance Minister Bill English said next week's Budget would confirm the Government was on track to surplus in 2014/15.
"Ongoing spending control will allow the Government to build up sufficient surpluses to provide choices around repaying debt and investing more in priority public services," he said.
But Greens co-leader Russel Norman said the Government's singular focus on one measure of economic performance - returning the Budget to surplus - was distracting attention away from its failure to rebalance the economy and create jobs.
