A relationship between two South Island iwi which goes back 161 years will be renewed on Tuesday at Otakou marae on Otago Peninsula.
The signing of an agreement between Te Atiawa o te Waka a Maui and Te Runanga o Ngai Tahu is a symbol of renewing historical ties which stem back to the Treaty of Waitangi in 1840.
Te Atiawa's treaty negotiator Sharon Gemmell says sadly after the treaty signing the relationship between the tribes broke down.
But she says in the past five years the iwi have worked alongside each other on fishery and aquaculture issues with the Crown.
Ngai Tahu chairman Mark Solomon says the values of both tribes are well aligned.
He says being close geographically means it makes sense for both iwi to formalise an agreement which recognises each tribe's mana and signals their desire to work together.
