A Māori rights group is off to Geneva to seek justice at the United Nations.
'Save Our Unique Landscape' was formed by south Auckland mana whenua in opposition to a 480-home Special Housing Area development on sacred land at Ihumatao.
Spokesperson Pania Newton told Newshub she'll be challenging the Crown.
"The coalition that is going over there will raise the fact that the Government have not met the requirements in the convention and that they continue to pass discriminatory laws here in Aotearoa."
The land's status as a Special Housing Area was upheld last year by Auckland Council, despite local Māori claiming it as wāhi tapu - sacred.
The group say land in question has historical, cultural and archaeological significance.
