The majority of residents in NSW believe women should be able to have an abortion and that they should be able to have it when they want to, according to a unique poll conducted on behalf of the NSW Greens.

In what is believed to be the first state-specific survey of its kind, the poll revealed that most people were unaware that abortion is still a crime in NSW, and the vast majority supported decriminalisation.

The results of the survey, which sought the views of more than 1000 people, cut across political, gender and geographical lines, according to Greens MP and spokeswoman for the Status of Women Dr Mehreen Faruqi, who will on Monday launch a campaign for abortion law reform.

"The polling sends a very clear message to all politicians, Liberal, National and Labor, that a vast majority of their constituents believe abortion should not be a criminal offence and women should be able to access clinics in safety and privacy without harassment and intimidation. They want abortion law reform in NSW," Dr Faruqi said.
