On the eve of a hui to consider a complaint against him, maverick Maori Party MP Hone Harawira has repeated calls for his party to pull support for the Government - and says he thinks tomorrow's hui will have serious consequences.

John Key's performance at Ratana's annual celebrations suggests he is confident National's relationship with the Maori Party is sound.

The National Government and its Maori Party partners presented a united face when Prime Minister John Key visited Ratana Pa this afternoon - a move Mr Key admitted was unexpected.

Phil Goff believes Ratana church followers are rallying behind Labour because of wider problems they see in NZ.

Maori party co-leader Tariana Turia says she is "totally unaware" of any leadership aspirations rogue MP Hone Harawira may have.

Maori Party leader Pita Sharples has said he and co-leader Tariana Turia are open to putting their leadership up for contest in the wake of public criticism from MP Hone Harawira.

Maori Party MP Hone Harawira believes his caucus colleagues are trying to crush opposition to the Government's legislation that will replace the Foreshore and Seabed Act and stop him voicing the concerns of his constituents.

MP Hone Harawira's Maori Party colleagues have laid a complaint against him.

An Act MP says the message is the same across NZ, "everyone, Maori and non-Maori, is vehemently opposed to this bill".

Parliament looks set to be debating foreshore bills for years to come after Labour pledged today to repeal the Government's legislation when back in power.

Labour has confirmed it will pull its support for new foreshore legislation, saying it does not offer a lasting solution.

In a way, the constitution is like a family bach which has been used for years and years.

Maori Party MP Hone Harawira says the bill that will replace the Foreshore and Seabed Act is a fraud because 98 per cent of Maori will not be able to meet the threshold to claim customary title.
