NZ First has given the sign-off for possible abortion reforms, but has pulled the pin on a referendum on MMP to lower the five per cent threshold for parties to enter Parliament.

After months of delay, a breakthrough on abortion reforms will see Cabinet soon consider a possible new regime that is expected to allow women to seek abortions by choice up to about 20 weeks.

Justice Minister Andrew Little confirmed he expected to be able to make an announcement in the next few weeks, after reaching agreement with NZ First this week.

That would allow legislation to be drawn up for all MPs to vote on. It would take abortion out of the Crimes Act and remove the barriers women currently have to go through.

That will be a conscience vote
