Doctors are experiencing a surge in the number of people asking for the drug Tamiflu, which can be used to treat swine flu.
The virus was confirmed in New Zealand on Tuesday, with official figures showing 13 known cases.
The Royal College of General Pracitioners says many GPs are fielding increased calls for Tamiflu prescriptions.
An Auckland GP, Dr Catherine McArthur, says four people without flu symptoms made appointments on Wednesday, hoping to get the drug. She turned them all down.
Until now, Dr McArthur says she has not been asked for Tamiflu for three years.
