The new government is being accused of putting people in danger with its decision to scrap the three strike laws for repeat offenders.

This from ACT, the party behind the introduction of the legislation, as part of its coalition agreement with National.

It compels judges to impose the maximum sentence possible for offenders who commit a third violent or serious sexual crime.

There's been criticism judges avoid the legislation because its flawed, and new Justice Minister Andrew Little has decided to scrap it.

But ACT leader David Seymour believes the government will have a lot to answer for.

"The early evidence is that three strikes has been deterring re-offending and it's very clear that if you are in prison, then it's incredibly difficult to harm the public," he said.

"Andrew Little is going to have to look in the eye of the families of victims of repeat offenders who could have been incapacitated.

"He is going to let some of the worst criminals out on the streets."

But Justice Minister Andrew Little says the legislation is having no impact whatsoever and there are better ways to prevent crime.

"Make sure that our correction system is doing the job we need to do, which is to change the people who have been anti-social, who have committed crimes, and stop them from doing that," he said.

"In the end, that's the way you make people safe."

Little plans to start the three strikes repeal by the middle of next year.
