Health Minister Tony Ryall said New Zealand's health system was "ready to respond" to any increased risk of bird flu.
"New Zealand has a pandemic plan which can be activated quickly if needed," he said.
"It is a whole-of-government plan with the Ministry of Health as the co-ordinating agency."
The ESR National Influenza Centre in Wellington is able to test for the flu, but no cases have yet been identified here.
"The WHO is working closely with Chinese authorities in their intensive surveillance and response to a number of cases where humans have contracted Avian Influenza."
Mr Ryall said there was currently no evidence of sustained human-to-human transmission, although travellers have been advised to limit travels to China.
