The government's operating deficit for the September quarter was wider than forecast, but Treasury said it expects this to reverse in coming months as the tax take ticks up.
The operating balance before gains and losses was a $343 million deficit in the three months through September, versus Treasury's forecast for a $279m deficit.
The government's tax take was $19 billion, slightly below the $19.1b forecast. Corporate tax revenue was below forecast by $300m, mainly due to 2018 income tax assessments lodged since June, indicating taxable profits in the 2018 tax year were lower than forecast, Treasury said.
"Tax revenue in the first quarter of the year tends to be less than what is recognised over the rest of the year, while expenses are generally more evenly spread across the year. As a result we expect the deficit reported in the September financial statements to reverse in the coming months," Treasury said.
Finance Minister Grant Robertson was also sanguine about the wider-than-expected deficit.
