For the June quarter, the seasonally adjusted current account deficit narrowed to $3.0b in the June 2021 quarter thanks to a lift in the value of exports.
The current account deficit was $2.2b narrower than the previous quarter due to an increase in value of goods exports (up $1.4b) and services exports (up $1.7b).
These increases to exports narrowed the goods deficit and the services deficit by more than $1.0b each.
Seasonally adjusted goods exports were worth $16.0b in the June 2021 quarter, a new high for the data series, Stats NZ said.
Stats NZ said that despite the turmoil of the Covid-19 pandemic, the value of New Zealand's international assets by the end of the quarter had increased by $33.0b compared with 30 June 2020.
The biggest driver to asset growth was portfolio investment assets, which increased by $49.9b, it said.
The annual deficit of 3.3 per cent of GDP was in line with market forecasts.
"That said, the deficit for the quarter was narrower than we and the market expected, which was equally offset by revisions to history over the balances for September 2020 through March 2021," Westpac economist Nathan Penny said.
For the quarter, both the goods and services balances lifted.
"From here, we expect the current account deficit to continue to widen as the deficit returns to its pre-pandemic levels," Penny said in a commentary.
Westpac expects it to reach its widest point of around 4.4 per cent of GDP in the second half of 2022, before settling at around 3 per cent of GDP over the long run.
