Abortion rates in New Zealand are falling but some women visiting abortion providers still face harassment and verbal abuse.
The Abortion Supervisory Committee, in its annual report released this week, said there was a "sharp decline" in the number of 15-19 years olds having abortions.
The committee said this was an encouraging trend. It partially attributed this decline to greater use of contraceptive implants.
However, the committee also said anecdotal evidence suggested many women with the subcutaneous implants inserted now wanted them removed due to side effects.
The implants were inserted in the upper arm, releasing the progestin hormone to prevent eggs leaving ovaries.
