The Maori Party has issued a word of caution to Labour leader, David Shearer, over his party's new housing policy.
If elected, Labour says it would try to curb rising house prices by barring non-residents from buying existing houses, flats or apartments.
They could purchase vacant land only if they commit to building a house on it.
Maori Party co-leader Te Ururoa Flavell said Mr Shearer should not talk about protecting whanau unless he's prepared to put his policy where his mouth is.
He labelled the Labour leader's policy as lip-service, and challenged the main political caucus to commit to real action by extending its policies to prevent the sale of land and strategic assets by any foreign ownership.
Mr Flavell said both Labour and National have a duty to look at how they can protect New Zealand's resources.
