Ngai Te Rangi has begun a postal vote of beneficiaries to change the way representatives are elected to the two Ngai Te Rangi tribal organisations.
Ngai Te Rangi is governed by two independent tribal organisations, each with a different way of electing representatives.
Te Runanga o Ngai Rangi Iwi Trust, which holds the tribe's fisheries assets, elects its representatives through marae-based electorates whereas Ngai Te Rangi Settlement Trust, which looks after the tribe's Treaty settlement assets, elects its representatives through hapu-community electorates.
Chair of both Ngai Te Rangi organisations, Charlie Tawhiao said the proposal was to replace the runanga's marae-based electorates with the Settlement Trust's hapu-community electorates.
He said one of the practical benefits would be that only one election process would be required in future.
