A net inflow of foreign investment helped lift New Zealand's net international liability position to $148.6 billion, or 72.6 per cent of GDP, June 30, from $145.6 billion, or 71.9 per cent of GDP, at March 31.
The government statistician said it also got new information on the value of overseas reinsurance claims from the Canterbury earthquakes. Total overseas reinsurance claims rose to $17.9 billion from $15.7 billion. Overseas reinsurers settled $1.3 billion of the claims in the second quarter, up from the $1.2 billion of settlements in the first quarter. Some $12.8 billion of claims is still outstanding.
ASB economist Jane Turner said the current account outcome was "a mild positive".
She expected the deficit to widen further over the next year to 6.5 per cent of GDP.
"The impact of the past decline in commodity prices is starting to work its way through the trade balance and ongoing recovery in the economy will lift the outflow of investment come.
"Heading into 2014, we expect goods and services trade to strengthen and start reducing the deficit."
A wider deficit over the next year would highlight the country's vulnerability to external financing, she said.
"However, gradual rebalancing of the economy is taking place. The private sector (via the financial system) is gradually reducing its net foreign debt.
" The Government is still increasing its use of foreign debt, but that will also change in the long term once budget surpluses are eventually restored."
