Rankin Treasury Advisory managing director Derek Rankin says poor jobs figures from Australia battered its currency.
He says the New Zealand dollar and the Australian dollar have both been in demand over the last week, mainly because of the testimony from Federal Reserve chair Janet Yellen.
Mr Rankin says there has also been some data that has come out that has been supportive of both the New Zealand and Australian dollars.
But he says the Australian jobs report came out on Thursday and 2700 jobs were lost, which was worse than expected.
Mr Rankin says unemployment rose to 6% which is the highest level since July 2003, which was lead to the Australian dollar dropping quite markedly.

Mr Marks says Fletcher Building shares were up and the trend has been to go higher over the last few weeks which could be due to positive housing data coming out of Australia and also the continued strength in New Zealand.

Mr Marks says Sky City had reasonable first half results, but there is a focus on cost-cutting, which the market probably sees as giving a limited long-term prospect for the company.
Fletcher Building shares rose 4 cents to $9.45, Commonwealth Bank is down 28 cents to $A75.92 and Sky City is up 1 cent at $3.66.
