Excluding investment gains and losses, the Treasury said the operating deficit stood at $1.624 billion for the five months to the end of November, compared with the $1.241b shortfall that had been forecast.
Treasury said the result is due to a weaker tax take from business, and lower interest income.
Core Crown tax revenue was 0.8 percent below forecast at $26.4b, with corporate tax $167 million below forecast, mainly as a result of weaker-than-forecast provisional tax in November, although Treasury said about a quarter of that was timing related.
Source deductions were $110m, or 1 percent, below forecast as a result of a larger-than-forecast seasonal decline in the November month, although this variance is expected to reverse out over the coming months.
Core Crown expenses stood at $30.5b, close to what was forecast.
Net debt stood at $63.5b, or 26 percent of gross domestic product.
After posting a $414m surplus last year - the first in seven years - the Treasury has forecasted a small deficit of $400m in 2016 due to the slowing economy and subdued inflation.
