Jacinda Ardern voted Australia's most trusted politician

Two weeks out from the general election, Australia says its most trusted politician is Jacinda Ardern.

In a poll by Millward Brown, 1400 Australians were asked to score 12 politicians across six areas: relevance, integrity, shared values, commitment, affinity and follow-through.

The clear winner of the 'Believability Index' was New Zealand's Ardern, who emerged with a score of 77/100 - streets ahead of second-place getter Penny Wong, who is Labor's leader of the Senate.

Former deputy Liberal leader Julie Bishop and Labor deputy leader Tanya Plibersek came in third and fourth respectively, meaning the most trustworthy politicians in Australia are all women.

The bottom five included Australia's former Prime Minister Tony Abbott and current Prime Minister Scott Morrison, 7 News reports.

Participants were also asked to name their preferred Prime Minister, although Ardern was not included as an option given she's busy running her own country. That title went to Bishop, who resigned from cabinet last year after a failed bid for the leadership.

A quarter of respondents said they weren't impressed by any of the listed politicians.

The Australian federal election will be held on May 18.
