Earlier this week, figures showed China's inbound shipments rose 6.3 per cent last month from June 2011, almost half the 11 per cent increase forecast in a Bloomberg survey.
"The New Zealand dollar may be unable to climb out of recent troubles today as the Chinese Q2 GDP data approaches," said Alex Sinton, Director Institutional FX at ANZ New Zealand.

The kiwi fell to 5.0355 yuan from 5.0773 yuan yesterday.
