Ngati Porou East Coast Rugby Football Union

The Ngāti Porou East Coast Rugby Football Union (NPEC) is a constituent union in the New Zealand Rugby Union located on the East Coast of the North Island. Its provincial team plays in the Heartland Championship and its home ground is Whakarua Park, Ruatoria. It is the smallest Union in New Zealand in the sense of player numbers and population base.

The union was previously called East Coast. Due to the high number of players from the Ngāti Porou iwi, the team became known as Ngāti Porou East Coast and in August 2023 the Union was officially renamed the Ngāti Porou East Coast Rugby Football Union on the New Zealand incorporated societies register.
