If you're planning a trip around Lake Waikaremoana today or tomorrow - you might need to think again.

Following those in Kutarere, Maungapohatu and Waiohou, a Waikaremoana group is to now demonstrate against the Tuhoe treaty settlement.

Ngati Ruapani ki Waikaremoana is set to close State Highway 38 over two days, with the Waikaremoana Great Walk at risk too.

The route from Murupara and Wairoa will be closed around the lake's shores between Onepoto and Hopuruahine today and tomorrow.

Anyone wanting to get to the East Coast will have to use State Highway 2 between Opotiki and Gisborne or the Napier-Taupo Highway.

One of the major grievances for the hapu is the fact it won't be granted seats on the board governing Te Urewera after the Treaty of Waitangi Settlement is signed.
