WELLINGTON, April 28 (Reuters) - New Zealand said on Tuesday it was monitoring a further 56 people for possible signs of swine flu.

The people have shown flu-like symptoms and were being tested to see if they have Influenza A, which is linked to swine flu.

"These are people who have been in Mexico or the United States in the last two weeks. They are people who may or may not have influenza A," Health Minister Tony Ryall told a news conference.

So far 10 people, nine students and a teacher from an Auckland school just back from Mexico, have been quarantined and treated as likely swine flu victims. Test results from an Australian laboratory are expected later in the week.

Three members of a group from a second school also just returned from Mexico have been cleared of any swine flu risk.

New Zealand has raised the level of its national pandemic plan and is screening all flights from North America.

The deadly swine flu strain has killed up to 149 people in Mexico and infections have also been found in the United States, Canada and Europe. (Reporting by Gyles Beckford; Editing by Jeremy Laurence)
