The Australian survey, scheduled for release at 1:30pm New Zealand time, may show that economy is still waiting for the effects of lower interest rates to feed through, Morgan said.
Traders are expecting the Reserve Bank of Australia to reduce the benchmark interest rate by 5 basis points over the next year, while New Zealand's central bank is expected to increase rates by 72 basis points over the same period, according to the Overnight Index Swap curve.
Meanwhile, the US dollar index, which measures the greenback against a basket of currencies, declined as Congress remained gridlocked over the budget and the Oct. 17 deadline approaches for the US to increase the nation's borrowing limit or risk a debt default.
The kiwi is probably headed up to 84 US cents over the next week or so, said OM Financial's Morgan.
"People are looking for a bit of yield around the world and all the data recently from New Zealand has been extremely positive and on a background of a weaker US dollar it is not surprising to see funds flow back into this part of the world," Morgan said.
The New Zealand dollar advanced to 80.69 yen at 8am in Wellington from 80.48 yen at the 5pm market close yesterday.
The kiwi rose to 61.34 euro cents from 61.08 cents yesterday and increased to 51.75 British pence from 51.67 pence. The trade-weighted index gained to 77.14 from 76.86 yesterday.
