Voter support for an Indigenous Voice to Parliament has suffered a hit since last year's federal election.

According to data published by The Australian, polling completed by SEC-Newgate Research suggests votes are currently six per cent less likely to vote yes in a referendum to constitutionally enshrine an Indigenous Voice in Australia's parliament when compared to data gathered nine months ago.

National support for The Voice has lessened from 59 per cent in May of last year to currently sit at 53 per cent, with a reduction in support from voters situated Queensland, South Australia and Western Australia a key factor.

The reduction comes after SEC-Newgate Research polled almost 1,500 people in the first week of February which determined that although remaining low, opposition to The Voice has risen six per cent to 22 per cent in the past nine months.

The data also showed that support for the Voice has dipped below 50 per cent in Western Australia and South Australia, results SEC-Newgate Research partner David Stolper said would worry the federal government.

"These results will concern the federal government, considering four of the six states have to be carried for the referendum to succeed," Mr Stolper said.

There is a significant discrepancy between Labor and Green supporters compared to Coalition voters, with the majority of Labor (65 per cent) and Green (77 per cent) voters in support of a Voice to Parliament compared to 32 per cent of Coalition voters.

Notably, 43 per cent of Coalition supporters are opposed to a constitutionally enshrined Voice.

The data was revealed in the same week Northern Territory senator Jacinta Nampijinpa Price quit the "No" campaign national committee she jointly launched with Warren Mundine and former Labor minister Gary Johns a fortnight earlier.

After abruptly leaving the six-member Recognise a Better Way committee, Ms Price will now head up a new No campaign funded by conservative activist group Advance Australia.

Following her resignation from Recognise a Better Way on Sunday, Senator Price said a "resounding No vote" would be achieved by the two campaigns working alongside one-another.

"I am deeply respectful of the national committee members themselves and the work they are undertaking, however I do firmly believe that my efforts are best directed towards the grassroots campaign focus of the Fair Australia campaign as opposed to the thought leadership and policy focus of Recognise a Better Way," she said.

"We are all committed to achieving a resounding No vote and in doing so a positive result for Australians."

Senator Price launched the Fair Australia Campaign on Monday, which is backed by a $1.45m budget and more than 77,000 signatories collected by Advance Australia.
