Te Pati Maori says claims against Manurewa Marae - say a lot about how its processes are viewed

The Public Service Commission is investigating claims information collected at the marae was used during the Party's election campaign -- which it denies.

Returning to Parliament for the first time since the claims emerged, Co-leader Debbie Ngarewa-Packer says the Party welcomes the review -- and stands by the marae.

She says it shows any time Maori try to do something to engage more people in democracy, they aren't allowed to do it the way they need to.
