A house in the Bay of Plenty and an Auckland spice shop have gone up in flames overnight.

Fire Service spokesman Daniel Nicholson said crews from Waihau Bay and Opotoki were on the scene in Waihau Bay where the house has completely burnt to the ground.

Crews are working to extinguish what's left of the blaze.

First reports of the fire came shortly after 5 this morning.


Meanwhile, Mohammed's Bulk Food and Spices in Mount Roskill caught fire just after midnight.

Firefighters said the building was fully involved when they arrived.
