The New Zealand dollar may extend its decline against its transTasman counterpart as Australia's currency rallies on rising commodity prices and the prospect of a stronger Chinese economy.
The kiwi fell to 79.17 Australian cents at 5pm in Wellington from 79.35 cents on Friday in New York. It traded at 82.94 US cents from 83.02 cents at 8am and 83.13 cents last week.
Australia's dollar may rally this week as government figures on Wednesday are expected to show consumers lifted their spending 0.3 percent in November from a month earlier, according to a Bloomberg survey, and as Chinese indicators show the world's second biggest economy may not face as steep a slowdown as initially feared.

"Australian retail sales this week should be slightly better than expected, and Chinese data should boost the Aussie dollar more than the kiwi," says Imre Speizer, market strategist at Westpac Banking Corp in Auckland. The New Zealand dollar may extend its decline to 78.75 Australian cents "as the Aussie outperforms", he says.
