World Health Organization is calling "a public health emergency of international concern."
The 25 students and teachers at Auckland's Rangitoto College returned to New Zealand via Los Angeles on Saturday.
Fourteen have shown flu-like symptoms, with four "more unwell than others," said Dr. Julia Peters, clinical director of Auckland Regional Public Health Service.
Health Minister Tony Ryall said 10 students tested positive for influenza A. The specimens will be sent to WHO to determine whether it is H1N1 swine influenza. H1N1 influenza is a subset of influenza A.
The WHO results are expected back by midweek. The group remains quarantined at home.
"It's certainly has not been confirmed that they have swine flu," said Dr. Craig Thoinley, medical officer of health in influenza. "We already have provisional information that some of the group have influenza A. We won't know if they have the type of influenza A that is swine flu."
According to the most recent reports, the number of confirmed swine flu cases in the United States stands at 11.
They include nine confirmed cases at or near the Mexican border in Texas and California, and an apparent outbreak at a private school in New York City.
All the patients have recovered or are expected to.
In Mexico, health officials said 81 deaths there were "likely linked" to the swine flu.
U.S. health officials said Friday that some cases of the virus matched samples of the deadly Mexican virus.
In response, South Korea said it will test airline passengers arriving from the United States. Japan will convene a Cabinet meeting Monday to come up with measures to block the entry of the virus into the country
