The British Home Office is drawing on New Zealand research for an independent review into the way rape complaints are handled by public authorities in England and Wales.
The review is looking at the entire process of a rape complaint, from the moment the attack is first disclosed until the court has reached a verdict.
To assist with the review, the Home Office has requested the results of a two-year Ministry of Women's Affairs research project.
Ministry chief executive Shenagh Gleisner says only 9% of New Zealand rape victims report a sexual crime, and of those only 16% go to trial and only 13% result in conviction.
She says the figures are similar worldwide.
The British review is being led by Baroness Vivien Stern, who will report back to the British government next month.
