China, New Zealand second-biggest export market, will release its official performance manufacturing index this afternoon. Last week, trans-Tasman currencies got a lift after the HSBC purchasing managers' index showed a gentler pace of contraction in Chinese manufacturing than expected, stoking optimism the world's second-biggest economy won't face as harsh a slow-down as feared.
Australia, New Zealand's biggest export market, will also release its PMI along with housing data this afternoon. The kiwi was little changed at 76.99 Australian cents from 76.92 cents yesterday at 5pm.
The New Zealand dollar edged up to 51.60 British pence from 51.52 pence yesterday after Moody's Investors Service cut its forecast for UK economic growth and said the government will struggle to meet its debt-reduction targets.

The New Zealand dollar fell to 65.75 euro cents at 8am from 65.96 cents yesterday. The kiwi fell to 63.11 yen from 63.35 yen.
