A Coalition MP in a marginal seat junked her how-to-vote cards on election eve, telling voters to direct preferences to the far-right, anti-multicultural Rise Up Australia Party.

Natasha Griggs is the Country Liberals member for the Darwin electorate of Solomon.

Labor has laid siege to the seat, which she holds by just 1.4 per cent, and leaders from both major parties have made multiple visits to Darwin over the eight-week campaign.

Her original how-to-vote cards instructed voters to direct second preferences to a Liberal Democrats candidate, but in an 11th-hour move, fresh cards handed out on the day before the polls now instruct voters to preference businesswoman Silvija Majetic from Rise Up Australia Party.

Rise Up is a Christian-based party, led by controversial Victorian preacher Danny Nalliah.

Mr Nalliah sparked controversy several years ago when he claimed the Black Saturday bushfires were God's revenge for Victoria's abortion laws.

He has also addressed a number of Reclaim Australia rallies over recent years.

Ms Griggs said she was aware the Northern Territory's Country Liberals Party was negotiating a new deal ahead of July 2.

"They were talking about a how-to-vote card for polling day," she told the ABC.

"I was aware there were discussions that were occurring, but I hadn't paid any attention to the how to vote.

"It's a matter for the party; it's got nothing to do with me."

In a pre-election candidate biography, Ms Majetic said: "I stand for Australian values, culture and way of life, which we can attribute largely to our Judeo-Christian heritage".

"I am sick of political correctness which is curtailing every Australian's right to freedom of speech."

Labor NT said it made a decision to preference Rise Up Australia below the Country Liberals, fearing its anti-multicultural platform would create division in the community.

"They've got some policies that we just don't agree with," ALP NT secretary Kent Rowe said.

"I think being anti-multicultural creates an unnecessary division and tension within this country, the strength of this country was built off everyone coming together.

"We just don't think [Rise Up Australia] should be supported at any level."

The ABC has sought comment from Country Liberals headquarters.
