Rising global dairy prices, the Canterbury rebuild and a stronger household sector supported the New Zealand economic growth outlook, which in turn had underpinned the currency, ASB said.
In contrast, the challenge for the Australian economy was the extent to which the non-mining sectors could pick up enough to offset the slowing mining sector.
"These differing growth prospects between NZ and Australia are supporting NZ/Australian dollar strength," the bank said.
ASB said 82.3 per cent of importers in the survey group expected the kiwi dollar to reach parity with the aussie over the coming year, compared with just 48.5 per cent of exporters surveyed.
The survey result was at odds with the ASB's economics department, which expects the NZD/Australian dollar to track around A93c to A94c over the next six months before easing.
However, the survey was more in keeping with the department's forecast for the NZ/US dollar.
Importers, on average, expect the NZD/US dollar to track US83c to US84c over the coming six months, before gradually easing to reach US81.4c by March, 2015.
Exporters, on average, expect the NZD/US dollar to ease over the coming year to reach US78.2c by March 2015.
The economics team expects a sharper easing in the NZD/US dollar rate over the coming year, as the US economy picks up and the Federal Reserve continues to withdraw monetary policy stimulus. ASB expects the NZD/US dollar rate to fall to US77c by March next year.
ASB said businesses' interest to hedge their currency risk had fallen in the latest quarter, driven by a decline in the proportion of exporters wanting to secure cover.
The bank said this was a likely reflection of growing confidence among exporters that the kiwi would ease against the US dollar over the coming year.
The ASB's Barometer tracks exporters' and importers' exposures to foreign exchange risk, through surveying businesses with annual turnover of at least $1 million.
