The New Zealand dollar gained as growth in the domestic economy partly offset weaker offshore news, including continued contraction in Chinese and Europe-wide manufacturing.
The kiwi dollar rose to 82.86 US cents from 82.44 cents at 5pm on Thursday. The trade-weighted index rose to 73.55 from 73.18.
The kiwi gained initially after the gross domestic product figures on Thursday, before selling off after the Chinese manufacturing data and subsequently recovering overnight.
The domestic economy grew 0.6 per cent in the second quarter, twice the forecast pace, driven by record milk production and increased building activity.
"The kiwi continues to draw support from the fact the NZ economy remains in better shape than most," said Mike Jones, currency strategist at Bank of New Zealand.
"We believe positive relative growth and interest rate differentials will support the NZD through to mid-2013."
New Zealand 10-year bonds are yielding about 3.64 per cent, or about 187 basis points more than comparable US Treasuries. The Federal Reserve is keeping its key interest rate target near zero, compared to New Zealand's 2.5 per cent official cash rate.
On Thursday, incoming Reserve Bank Governor Graeme Wheeler and Finance Minister Bill English signed an updated policy targets agreement that keeps the focus on price stability and doesn't attempt to give the bank a greater role in trying to rein in a strong kiwi dollar.
The kiwi rose to 63.84 euro cents from 63.39 cents on Thursday, to 64.85 Japanese yen from 64.39 yen and to 79.40 Australian cents from 79.17 cents.
