Contraception

Contraception gives you control over if and when you want to become pregnant. There are many safe and effective options available in Aotearoa New Zealand, ranging from long-acting methods you don’t have to think about, to short-acting and barrier methods that you use when needed.

Choosing the right contraception depends on your health, preferences, and future plans.

Long-acting reversible contraception (LARC)

These methods are the most effective forms of contraception and last for years, but can be removed at any time if you want to become pregnant.

Intrauterine devices (IUDs)

  • Copper IUD

    • Non-hormonal
    • Works for 5 years
    • Can make periods heavier or more painful for some people

  • Hormonal IUDs (Mirena®, Jaydess®)

    • Release a small amount of progestogen into the uterus
    • Mirena® lasts up to 8 years (also helps with heavy periods)
    • Jaydess® lasts up to 3 years
    • Periods usually become lighter and less painful

Contraceptive implant (Jadelle®)

  • Two small rods placed under the skin of the upper arm
  • Lasts for 5 years
  • Highly effective and easily removed if needed
  • Can cause irregular bleeding, especially in the first months

Hormonal contraception

These methods use oestrogen and/or progestogen hormones to prevent pregnancy. They work well if taken correctly, but require more regular use than LARC.

Combined oral contraceptive pill (“the pill”)

  • Contains both oestrogen and progestogen
  • Taken daily
  • Can regulate periods, reduce period pain, and improve acne
  • Not suitable for everyone (e.g. migraine with aura, certain health conditions, or smokers over 35)

Progestogen-only pill (mini-pill)

  • Taken daily, at the same time each day
  • Suitable for those who cannot take oestrogen
  • Periods may be irregular or lighter

Contraceptive injection (Depo-Provera®)

  • Given every 12 weeks
  • Convenient if you prefer not to take a pill daily
  • May cause irregular bleeding at first, often leading to lighter or no periods over time
  • Fertility can take several months to return after stopping

Barrier methods

Barrier methods prevent sperm from reaching the egg. They are less effective than LARC or hormonal methods but can be useful, especially for occasional contraception.

  • Condoms (male or female)
    • Protect against both pregnancy and sexually transmitted infections (STIs)
    • Widely available and easy to use
  • Diaphragms
    • Less commonly used in NZ
    • Must be fitted correctly and used with spermicide

Permanent contraception

If you’re sure you do not want more (or any) children, permanent options are available.

  • Tubal ligation — an operation to block the fallopian tubes
  • Salpingectomy — an operation to remove the fallopian tubes
  • Vasectomy — a simple procedure for men that blocks the tubes carrying sperm

These methods are highly effective and intended to be permanent.

Emergency contraception

If you’ve had unprotected sex or your usual method has failed, emergency contraception can help prevent pregnancy if taken in time.

  • Emergency contraceptive pill
    • Works best the sooner it’s taken (up to 3–5 days depending on the pill)
    • Available at pharmacies, GPs, and family planning clinics
  • Copper IUD
    • Can be fitted up to 5 days after unprotected sex
    • The most effective emergency contraception option
    • Can be left in as ongoing contraception

Finding the right option for you

Every method has its pros and cons. Things to consider include:

  • How effective it is
  • Convenience (daily pill vs long-acting methods)
  • Side effects and health conditions
  • Whether you also want protection from STIs
  • Your plans for future pregnancy

We can discuss all options with you and help you choose the method that best suits your lifestyle and needs.

Contraception services in New Zealand

  • Many methods are subsidised or free if you are eligible for publicly funded healthcare.
  • Services are available through GPs, Family Planning clinics, sexual health services, and some pharmacies.
  • In my clinic, I provide specialist advice and access to procedural anaesthesia.

FAQs

What is the most effective form of contraception?
Long-acting reversible contraception (LARC) like the hormonal IUD (Mirena), copper IUD, and the contraceptive implant (Jadelle) are the most effective methods, with a success rate of over 99%. They are "fit and forget" options that work for years.
Will getting an IUD hurt?
The insertion can cause some cramping and discomfort, similar to strong period pain. We can discuss pain relief options, like using local anaesthetic or other medication, to make the procedure as comfortable as possible. Most people find the discomfort is brief and manageable.
How quickly does my fertility return after stopping contraception?
For most methods, including the pill, implant, and IUDs, your fertility can return to normal very quickly after removal. With the contraceptive injection (Depo-Provera), it can sometimes take several months for your regular cycle to resume.
Do I still need to use condoms if I have an IUD or am on the pill?
While hormonal contraception and IUDs are excellent for preventing pregnancy, they do not protect against sexually transmitted infections (STIs). Using condoms is the best way to protect yourself from STIs, especially with new partners.
Which contraceptive method is best for me?
The best method is one that fits your lifestyle, medical history, and personal preferences. We can have a detailed discussion about the pros and cons of each option to help you make a choice you feel confident and comfortable with.
