The Local Government Commission has upheld Horizons Regional Council's proposal for representation arrangements for local body elections in October.
Following the regional council's representation review last year, the Commission has backed Horizons' final proposal for a 14-seat council, including two new Māori seats.
It says the arrangements provide effective representation of communities of interest and fair representation for voters in the Manawatū-Whanganui region.
Horizons will keep its existing six general constituencies of Ruapehu, Whanganui, Manawatū-Rangitīkei, Palmerston North, Tararua and Horowhenua, and bring in two new Māori constituencies: Raki Māori (Māori North) and Tonga Māori (Māori South).
The Commission's determination announced yesterday follows a hearing in February into the single appeal against the council's final representation review proposal.
