The area they can claim stretches from high tide mark to 12 nautical miles out. They can seek those rights either from the Crown or through the High Court, and they have to register their interest before April 3 next year.
Mr Paki said an attempt to get those rights has been in the Rakautaua long-term plan for three years. It was new to some of those at Tini Waitara, but they were interested in pursuing a joint claim.
What is yet to be decided is how big an area to ask for - how far out to sea and far along long the coast. Mr Paki said it could potentially stretch as far south as Foxton.
To the north, Whanganui iwi have registered an interest that stretches to Kaitoke.
"Māori in Whanganui are putting in a submission as well, and there seems to be a bit of overlap."
Lots of other iwi had made claims, and the Whangaehu-Turakina claim could be one of the last to register.
