Seven flights have been disrupted at Auckland's domestic airport after a woman evaded security.

The Aviation Security Service says the woman went through an unmanned walk through metal detector at the terminal, unscreened.

Security screening was brought to a halt this afternoon while staff examined CCTV footage to track her down.

Two Jetstar flights and five Air New Zealand flights were delayed in the interim.

All passengers on the pier had to be re-screened - and passengers had to be taken off a Jetstar plane.

Queuing chaos ensued with an estimated 500 people affected.

Police are waiting at Wellington Airport to interview the woman upon her arrival.

The plane she was travelling on will also be searched as a precaution.
