Many wars have been fought over a line on a map.
In this case I don't see Te Arawa or Raukawa going to battle but a war of words has broken out.
The Te Arawa River Iwi Trust has accused the South Waikato iwi of modern day imperialism for trying to claim land by association beyond its area.
However, the Raukawa Settlement Trust says all the map does is acknowledge the close whakapapa connections to its neighbours, Te Arawa and - according to the map - part of Tuwharetoa.
The map in question covers an area just south of Tauranga Harbour, encompasses almost of Lake Rotorua and borders the northern shore of Lake Taupo, taking in part of the Kaingaroa Forest.
