A child who arrived in New Zealand from North America has been diagnosed as the first new case of swine flu in three weeks.
The youngster flew into Auckland on Sunday and is isolated at home while being treated with Tamiflu.
Director of public health Mark Jacobs said it was the first new case since May 15 and officials were working to trace other passengers from flight NZ1.
"The cumulative total of confirmed cases in New Zealand is now 10, and the cumulative total of probable cases is now 10."
There were also 27 suspected cases - down three from the last Friday.
All nine confirmed cases in New Zealand have now recovered.
Meanwhile, an American scientist says he was misquoted in reports claiming the swine flu virus may have originated in New Zealand.
"The statement was based on early phylogenetic analysis of available sequences. It was misquoted," Professor Gus Kousoulas of the School of Veterinary Sciences at Louisiana University said.
"There is no basis currently to support a New Zealand origin. While we still do not know the true origin, a US or Mexico origin is more likely."
Australia's swine flu tally has meanwhile passed 400 as Victoria recorded a massive surge in cases, most of them children aged 5 to 18, prompting a 12th school in the state to be closed on Monday. Two schools in Cairns will also close this week after two 13-year-old girls tested positive.
New Zealand schools are being warned they may have to close if students test positive for swine flu.
