There's been a fire at the Heinz Wattie's plant in Hastings.

It broke out at about 2am in an outdoor covered area at the production facility in King Street North, in the centre of town.

Five fire trucks from Napier and Hastings were sent, and three are still there.

Fire Service spokesman David Meikle says the cause is not yet clear but an investigator is on the way.
