But the Whangarei branch of Voice for Life New Zealand says women need more information when they visit a doctor for a termination.
"The ALRANZ statement that not restricting abortions will reduce them just doesn't make sense," Whangarei spokesman Steve Jaunay said.
"Figures in New Zealand show that almost 50 per cent of women who have abortions do so as a result of failed contraception, in fact; a large percentage hadn't use contraception at all."
Mr Jaunay said in an Australian-New Zealand survey, 60 per cent of young girls reported losing their virginity while drunk.
"There is no proof that increased access to contraception will lower the abortion rate. The heart of the problem lies in responsible decision-making with regards to issues like youth alcohol as well as relationships and sexuality and exposure to risk," Mr Jaunay said.
"The ALRANZ solution of throwing free contraception into the mix is simplistic and not well thought through, and in fact rather than help the situation may well exacerbate it. Our view is free contraception will not lower the [termination] rates."
Mr Jaunay said doctors needed to tell women about research linking mental and emotional disorders with abortion.
