So what if the track back to a fiscal surplus is proving longer and more uphill than it looked a year or even six months ago?
The Government will not be changing its fiscal policy settings in the May 21 Budget just because the Treasury is now expected to forecast a "slightly" bigger deficit in the current year than the $572 million it did last December and a "slightly" smaller surplus in 2015/16 than the half-year forecast of $565 million, Finance Minister Bill English said yesterday.
"We will not be pursuing cuts in services or income support in a kneejerk response to lower tax revenue."
And it will be sticking with the $1 billion allowance for new spending in this year's Budget and again in next year's.
Rightly so. The sums we are talking about, while large in absolute terms, are well within the margin of error when forecasting the difference between two large numbers with a lot of moving parts. They are less than 1 per cent of revenue or spending, and a fraction of 1 per cent of gross domestic product. It is the direction of travel that matters for the financial markets and that has been clear. In 2011 the deficit was the equivalent of 9 per cent of GDP, swollen of course by the earthquakes. It has halved, relative to the size of the economy, every year since then.
