Contraceptive implant

Kuhinga ārai hapū

A contraceptive implant is made up of two small, flexible rods that are put under your skin and release small amounts of the hormone progestogen. The implant works by thickening the mucus in your cervix and may stop your ovaries releasing an egg.

The implant is very good at preventing pregnancy (99%) and lasts up to five years.

A trained GP or nurse puts in the implant using a local anaesthetic. You can have it removed at any time.

Your periods may become irregular or longer than usual. Particularly in the first six months.

See your general practice, Sexual Wellbeing Aotearoa Clinic, school clinic or Te Tahi Youth to find out if it's right for you.

Sexual health visits with your general practice team may be free. Ask your general practice team if you are eligible.

Appointments at Sexual Wellbeing Aotearoa Clinics are free for New Zealand residents if you are under 22.

Te Tahi Youth offers free medical care and counselling for those aged 10 to 24.
