Ross Weston, a senior trader at Kiwibank, said the market may have been expecting a poorer number and so it rallied on the news, in particular, the revisions.
He noted, however, trading is very light and the GDP data was the last major event "before New Zealand shuts down for the holiday period."
While there will be little to push the kiwi around in the next few sessions, thin trading can increase volatility, he said.
Looking ahead, he said some US data due at the end of the week will be closely watched for direction, including the third-quarter GDP revision, durable goods orders and the trimmed mean PCE inflation rate.
The kiwi rose to 79.46 yen from 78.76 yen yesterday after the Bank of Japan kept monetary policy steady on Thursday despite growing signs of strength in the economy, signalling that it was in no rush to edge away from crisis-mode stimulus with inflation still distant from its 2 per cent target.
It traded at 91.39 Australian cents from 90.89 cents yesterday and at 4.6018 Chinese yuan from 4.5903 yuan. It traded at 59.04 euro cents from 58.74 cents yesterday and rose to 52.42 British pence from 51.96 pence.
New Zealand's two-year swap rate lifted 2 basis point to 2.19 per cent and the 10-year swaps rose 4 basis points to 3.15 per cent.
