"We have had a particularly strong day against the likes of the Australian dollar which under-performed on some slightly weaker than expected CPI numbers," said ANZ Bank New Zealand senior economist Philip Borkin. "That helped drive the TWI up," he said.
The strong kiwi/Aussie cross pushed the trade-weighted index to 79.18 from 78.96 yesterday. "That cross was the main driver today," said Borkin. He said it was difficult to envisage the kiwi falling much against the Australian dollar, at least in the short term. "I think things are certainly improving in Australia ... but at this stage, New Zealand is still shining ahead."
Borkin said there were no major data overnight that might push the kiwi around although markets would continue to watch for any clarity from US President Donald Trump. He said the next major event for the kiwi is Thursday's domestic CPI data, where economists are expecting inflation to move back into the central bank's 1 per cent to 3 per cent target band for the first time in more than two years.
New Zealand's two-year swap rate was unchanged at 2.37 percent, and 10-year swaps were up two basis points at 3.45 per cent.
The kiwi rose to 4.9816 Chinese yuan from 4.9622 yuan. It rose to 67.50 euro cents from 67.29 cents Tuesday. It edged down to 57.80 British pence from 57.83 pence and rose to 82.27 yen from 81.60 yen Tuesday.
