ACT is criticising ACC measures that aim to reduce disproportionate workplace injuries among Māori and Pasifika.

It's written to the ACC Minister, asking if targets with an ethnic focus match a Cabinet requirement for need-based public service.

Act MP Laura McClure says she hasn't seen evidence to back the targets.

"It's completely lazy - and I actually think it is a bit racist to say one particular group of people needs specific targeted training."

ACC says it's confident its services are based on need, not race.
