Chasing runaway koi carp in the Kaipara's Lake Taharoa

Koi carp contribute to poor water quality and a serious problem in both New Zealand and Australia. This week a koi carp has been spotted by a 10 year old boy fishing in the 50,000 year old dune Lake Taharoa in the Kaipara District of Northland. Authorities are alarmed by the sighting of koi carp as Local Democracy's Northland reporter Susan Botting explains.
