The divide between the Rimutaka and Tararua ranges has been officially named Remutaka Pass "in keeping with the heritage and place-naming traditions of local iwi", according to Land Information New Zealand.
Land Information Minister Louise Upston on Friday confirmed the new name, which was considered by the New Zealand Geographic Board Nga Pou Taunaha o Aotearoa (NZGB) after being proposed by former Masterton Mayor Frank Cody.
Mr Cody made the proposal as a member of the Remutaka Pass Co-ordinating Group. The pass is the lowest point between the Rimutaka and Tararua ranges. The initial motivation for naming the pass, according to the group, was to help in its promotion as a scenic drive.
"Remutaka is the original Maori name for the feature. It commemorates the edge [remu] of Haunui-a-Nanaia's cape falling to the ground [taka] when he first viewed and named Wairarapa," NZGB secretary Wendy Shaw said.
"The name recognises its historic significance to mana whenua, and the pass's traditional use by Maori to pass from the Hutt Valley to the Wairarapa."
