Hon GRANT ROBERTSON: New Zealanders' confidence in the recovery has been confirmed via an increase in tax revenue. Tax revenue was $89 billion in the 11 months to the end of May 2021, $4.1 billion above forecast. The improvement was across the board, with corporate tax being 13.7 percent higher than expected, source deductions revenue up 2 percent on forecast, and GST up 2.5 percent. Treasury notes that the positive variances reflect economic conditions being better than forecast. In simple terms, businesses are benefiting from New Zealanders buying their goods and services, which allow them to employ people, which in turn boosts spending in the economy. Nevertheless, the outlook does remain uncertain. The recent case of the Australian traveller in Wellington with COVID-19 and Australia's growing outbreak, which has prompted the alert level rises, are signs that a resurgence in COVID cases around the world can make the economic environment more volatile, and we need to be cautious in response to that.
