If you're using a woodburner to heat your home, you'll need firewood. Suppliers usually advertise in the classified section of the Mountain Scene newspaper. Be sure to order well in advance to allow the firewood to dry out fully – and be aware wood suppliers sometimes run out of dry wood towards the end of winter.
You can buy wood pellets for pellet burners at hardware stores, supermarkets and at some petrol stations.
Note that in Arrowtown, to meet clean air regulations your woodburner must comply with Otago Regional Council efficiency and emission standards and you are not permitted to burn coal.
