Two caravans have been lifted and one person is trapped at a Northland holiday park in what is being described as a "mini tornado".

One person is understood to be injured.

Fire and Emergency said they were called to Tauranga Bay Holiday Park about 9.15am on Tuesday.

They had four appliances there.

St John's said they were also at the scene.

MetService said intense rain and thunderstorms in the area meant there was the potential for a tornado.

But a spokesperson could not say whether one had occurred.

However, wind gusts of up to 75km/h had been recorded in the Kaeo area.
