The local currency was largely unchanged when Statistics New Zealand reported the consumers price index increased a quarterly 0.4 per cent in the second quarter while annual inflation was 1.5 per cent, slightly lower than economists' expectations but in line with central bank forecasts.
However, it gained later in the session when the Reserve Bank said its quarterly sectoral factor model advanced 1.7 per cent quarter on quarter, the strongest since the June 2011 quarter.
According to the central bank, the model estimates the common component of inflation in the CPI basket, the tradable basket, and the non-tradable basket, based upon separate factors for the tradable and non-tradable sectors.
"They have said that gauge is one of their prefered measures of core inflation," said Martin Rudings, senior dealer foreign exchange at OMF, adding that the Bloomberg headlines on the data "essentially stopped the US dollar from rising in Asia."
The central bank is mandated with keeping annual inflation between 1-and-3 per cent over the medium term, focusing on the mid-point.
However, inflation has remained stubbornly weak and the central bank has signalled the official cash rate is likely to remain at a record low 1.75 for some time to come given the lack of inflationary pressure. Markets had moved to price in the possibility of a rate cut on the back of weak data.
The kiwi also benefited from a softer Australian dollar after the Reserve Bank of Australia's latest minutes highlighted risks around record household debt.
Rudings said the kiwi could continue to push higher against the Aussie but its move against the greenback may be tempered by Federal Reserve chair Jerome Powell's testimony to the Senate on monetary policy if he continues to be upbeat on the US economy.
