Karamatura Heritage Farm is a heritage farm at 1230 Huia Road in Huia, in the Waitakere Ranges, run by a volunteer trust. The trust was set up in 2005 to preserve the rural landscape and the farming heritage of the settlers in the Karamatura Valley. It keeps old agricultural equipment and farms heritage livestock and poultry, and it is linked to the Huia Settlers Museum. The trust holds a licence from Auckland Council to graze eight hectares of Auckland Regional Farm Park land, for old breeds of livestock and poultry only. The land stays open to the public under the usual regional park terms. The trust has also planted 40 heritage fruit trees on the property.
The farm's main public event is the Farm Day on Waitangi Day, run by volunteers to raise money for the trust. Activities listed for it include tractor rides, pony rides, sheep shearing, tug of war, a waterslide, petting animals, butter making, flax weaving, wool spinning, a bee display and a sausage sizzle. Visitors are asked to bring a picnic lunch, gumboots in case it is wet, and togs for the waterslide. There is plenty of parking, and donations are welcome. To reach the farm, drive through Huia Village, over the bridge and up the hill, following the signs. For a family in west Auckland who wants a heritage farm day out, the Waitangi Day event is the main public occasion.
