The New Zealand gained against the Aussie after disappointing business confidence across the Tasman and extended its gains against the greenback on speculation Adrian Orr will make a more hawkish next governor of the Reserve Bank.
The kiwi gained to A91.96c at 5pm from A91.75c at 8am and A91.53c late yesterday. It was at US69.27c at 5pm versus US68.86c late yesterday.
The kiwi pushed higher against the Aussie after business confidence eased across the Tasman. National Australia Bank's index of business conditions fell 9 points to +12 in November, unwinding all of October's surprise spike.
The kiwi also continued to benefit from news that NZ Superannuation Fund chief Orr had been named RBNZ governor after a unanimous recommendation from the bank board.
Ross Weston, a senior trader at Kiwibank, said the kiwi was "defying logic" as it should be moving in the other direction "in the shadow of the Fed", given the US Federal Reserve is expected to hike US interest rates on Thursday morning New Zealand time.
