The Maori Party says it understands the frustration that has driven Maori sovereignty campaigners to call for a month-long civil disobedience campaign, but does not support targeting people in their homes.
The Sunday News yesterday reported a campaign - led by MP Hone Harawira's uncle Tass Davis - would involve targeting the homes of high-profile judges and occupying courtrooms to draw attention to calls for a Maori sovereign nation.
Mr Davis, a 75-year-old former Auckland police constable, said he expected between 300 and 400 Maori would be involved in the non-violent campaign.
Maori Party co-leader Tariana Turia said targeting individuals, who work for the state, in their homes was "not the way forward".
However, everyone had a democratic right to protest and her party understood the frustration of the campaigners.
"We accept that there is no desire to create fear and that this action is about justice denied."
Ms Turia said campaigners were worried about "successive governments' inaction" regarding the Treaty of Waitangi, specifically its interpretation.
Prime Minister John Key said today he was concerned judges may be targeted at home during the campaign and he warned protesters to keep their activities within the law or face police action.
He said he had no problem with peaceful protests.
"But once they start breaking the law they are over the line. They really shouldn't be undertaking illegal activity and no one should be encouraging them to," he told TV One's Breakfast.
Mr Harawira has spoken in support of his uncle.
"I will not tell my uncle not to do this. If he feels passionate about it, then I say more power to him."
