Despite bowing out of a political run as an independent in August after claiming he had "no reasonable prospects of success" due to changes in Commonwealth election legislation, Mr Mav has high hopes for a run at the Senate under Ms Hanson's lead.

"She will be the leader. I will follow her all the way, but she's made it very clear to me that when it comes to Tasmanian policy, she will be deferring to me," he said.

Ms Hanson also characterised the numerous controversies surrounding Mr Mav as "frivolous".

He has denied allegations he "ripped off" a Western Australian Aboriginal alliance in 2015.

Mr Mav and Jacqui Lambie Network will be competing for Liberal stalwart Eric Abetz's seat after he was relegated to the party's number three spot earlier this year.

When asked what policies the new union had in mind for the state, Mr Mav referenced his long-running push for federally funded super-clinics, but was unable at this stage to outline a more comprehensive Tasmania-focused policy.

Likewise, when the same question was put to Ms Hanson, she couldn't point to any further plans, saying only that the two will begin rolling out policies in the coming months.

One Nation intends to field candidates in all five Tasmanian House of Representative seats, despite both Hanson's Party and Mr Mav failing to sufficiently motivate Tasmanian voters in recent years.

"Not having candidates in every seat at the last election delivered a disappointing result, but members have been more than willing to put their hands up for candidacy ahead of next year's poll," Ms Hanson said.

"In the two seats we did run candidates, One Nation averaged 6.835% of the vote. If that can be replicated across all five lower house seats or better, we're most certainly in for a chance to pick up a Senate seat.

"You can't beat Steve's passion for Tasmania and he discussed in great detail the need for the state to introduce four federally funded super-clinics that resonated with me and others on the pre-selection panel."

In the event that he wins, Mr Mav has pledged to establish his government office in Launceston as part of a shift in focus to voters in the North, following a failure to drum up support down South.

Mr Mav denied that his move to One Nation was simply to keep from being listed below the line as an ungrouped independent during the election, saying his conservative views lined up with the party's.

When asked what views in particular, Mr Mav noted their joint stance against mandatory vaccinations and so-called "mass immigration".

The last date a normal house and half-Senate federal election can be held is May 21 next year.
