Contraceptive implant

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 (numbing). 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 GP or Family Planning Clinic to find out if it's right for you.

Sexual health visits with your GP may be free. Ask your GP if you're eligible.

Appointments at Family Planning Clinics are free for New Zealand residents if you're under 22.
