The Health Minister's promising to check measures designed to make healthcare more equitable are working.

A new equity adjuster-waitlist tool - trialled at two hospitals - includes ethnicity as a factor in criteria, coming after medical need.

The ACT Party has labelled it racial discrimination, and the Prime Minister is now pausing further rollout of the scheme.

Minister Ayesha Verrall says they need to ensure it's not having any unintended consequences.

"There is discrimination in the health system that means some people are getting treated later than others. This has been implemented to try and address that."
