Income tax, which makes up the bulk of tax revenue, was 1.1 percent ahead of forecast at $13.21 billion. Corporate tax was 5.9 percent below forecast with provisional taxes running behind expectations, which officials said could be timing related and may reverse later in the financial year.
The Treasury predicts the Crown's obegal will slip back into deficit in the 2016 financial year before returning to smaller surpluses further out as tepid inflation and a lack of wage growth keeps taxes flatter than expected. Finance Minister Bill English has relaxed his focus on avoiding red ink, saying he won't distinguish between small surpluses or deficits in the immediate future.
The Crown's residual cash deficit was $913 million ahead of forecast at $7 billion, with $931 million of unanticipated spending on personal and operating costs in the half. Treasury said a large proportion of that was due to timing of payments over the Christmas period, and should reverse out in January.
The blow-out in the cash deficit meant the Crown's net debt was $1.1 billion more than expected at $66.93 billion, or 27.5 percent of gross domestic product. Gross debt was $615 million less than forecast at $85.75 billion, or 35.2 percent of GDP.
The operating balance, which includes movements in the Crown's investment portfolios, was a bigger deficit than forecast at $1.98 billion, due to higher than expected actuarial losses on the Accident Compensation Corp's forward liability. The ACC liability was valued at $32.23 billion as at Dec. 31, $562 million more than forecast, and ahead of the $31.28 billion a year earlier.
The Crown's net worth at $84.32 billion was $866 million less than expected due to the bigger operating deficit.
