Jacinda Ardern says abortion law should be removed from the Crimes Act. That's all she's said so far in regards to Labour's policy around abortion.

A Down syndrome advocacy group has impersonated the Labour Party in a social media campaign that includes false information about the party's abortion policy.

The issue of abortion resurfaced following Monday night's leaders debate, with Labour leader Jacinda Ardern saying, if elected, she would decriminalise abortion by removing it from the Crimes Act.

"It shouldn't be in the Crimes Act. People need to be able to make their own decision," she said.

FACEBOOK A disabilities advocacy group has created a false campaign ad with a false statement relating to abortion policy. Labour says this is not their policy and it's not their campaign material.

"I want women who want access to be able to have it as a right."

Following Ardern's comments Saving Downs issued a statement saying it was concerned about Labour's plans to change abortion law.

STUFF From leaders resigning, to scandals and bizarre jabs, the 2017 election campaign has been one for the books.

The statement also included an incorrect claim that Labour planned to introduce abortion for disabilities to 40 weeks, or birth.

On Wednesday, Ardern repeated that was not the party's position.

Labour would remove abortion law from the Crimes Act and include all regulations within separate abortion legislation, she said.

She did not say anything about the party extending access to abortion to 40 weeks.

Despite this, Saving Downs created a social media post using Labour's campaign slogan (Let's do this), Labour's logo, and Labour's leader.

The graphic says: "Abortion up to birth for babies with disabilities", followed by the slogan "Let's do this".

A Labour spokesman said the party had contacted Saving Downs head Mike Sullivan, asking him to remove the post that contained the false claim alongside Labour branding.

The party had contacted Facebook and Twitter asking them to remove the posts.

And it had sought advice from the Electoral Commission regarding the laws relating to people or organisations impersonating a political party or its brand.

This is fake news. Jacinda doesn’t support abortion up to birth for babies with disabilities. We’ve asked the organisation to take it down. — New Zealand Labour (@nzlabour) September 6, 2017

On Thursday, Sullivan said he did not plan to remove the posts, which were created shortly before midday on Wednesday.

If Saving Downs was contacted by Facebook, Twitter or the Electoral Commission it would seek legal advice, he said.

Sullivan said the social media campaign was aimed at getting Labour to clarify its position around whether it would change the current laws around abortion relating to disabilities.

The group said other jurisdictions that had decriminalised abortion then went on to extend the cut-off period for late-term abortions for disabilities and it was concerned the same would happen in New Zealand.

Sullivan, who has a daughter with Down syndrome, says if a future government did extend late-term abortions for disabilities, it would be discriminatory.

Bill English said he did not seek to change abortion laws but if a bill came before the House, MPs would be free to vote their conscience.

Ardern said her party would find a way to remove the law from the Crimes Act but when it came to other proposed changes, MPs would be able to vote their conscience.
