Two pamphlets were distributed in central Wellington over the week.

Leaflets distributed around Wellington's northern suburbs are full of "disgraceful, despicable racist bigotry", and should be thrown in the bin, MP Peter Dunne says.

Pamphlets promoting a campaign named Rolling Thunder were distributed to homes in Dunne's Ohariu electorate this week, bearing the slogans "no special representation of part-Maoris in local government" and "end the stranglehold that one minority group has over the culture and life of the nation".

Dunne said it was the second pamphlet about Treaty of Waitangi issues that had been dropped in letterboxes in his electorate in recent days.

"I acknowledge the right to free speech," he said. "But I am nonetheless outraged that this type of nasty, racist drivel is being circulated by some anonymous group.

"I encourage people who are equally offended that racists are at work in our community to show them and their publications the time-honoured order of the bin.

Supplied MP Peter Dunne is appalled racist propaganda was delivered to homes in Wellington.

"Ohariu is a vibrantly multicultural electorate, and the views expressed in these leaflets stand in stark opposition to the values I have had continually expressed to me by the people of this diverse, open and tolerant electorate.

"I suspect the group is trying to capitalise on the fears displayed in other countries, but I think New Zealand is bigger and better than that," he said.

On the pamphlet the group states contributions can be made to an Orewa bank account, and claim further information can be found in books such as One Treaty, One Nation – a recent publication from Tross Publishing, and written by Hugh Barr, Don Brash, and others.

DAVID WHITE/FAIRFAX NZ The Rolling Thunder leaflets reference a work co-written by former National Party and ACT leader Don Brash. However, Brash said on Thursday that he had nothing to do with the group.

Barr stood for NZ First in Ohariu at the 2011 election, and has been outspoken on Maori foreshore and seabed policies.

Former National Party leader Brash launched the Hobson's Pledge Trust campaign last year, which called for an end to separatism and race-based laws.

He said on Thursday night he had nothing to do with the Rolling Thunder campaign, and neither did the Hobson's Pledge Trust.

"I do, of course, strongly favour New Zealand's being a colour-blind society, where all citizens have the same constitutional status," he said.
