Also known as self-injury

Self-harm is when you hurt your body on purpose to cope with feeling distressed and you don’t know how else to express your feelings.

Key points

  1. Self-harm is about finding a way to cope in order to keep living; it’s not an attempt to commit suicide.
  2. If you are self-harming, it’s important that you get help: More than half of the people who die by suicide have a history of self-harm.
  3. Self-harm is quite common, especially in young people. A Youth 2000 survey found that in 2012, 29% of female high school students and 18% of male high school students in New Zealand had self-harmed in the past 12 months.
  4. If you are self-harming, it’s important to know that there is help for you and there is hope that you can stop doing it.
If you have seriously injured yourself, or taken something poisonous or overdosed on medicine or drugs, call 111 and ask for an ambulance.
If you are trying to stop yourself from hurting yourself right now, you can get help from your local DHB’s mental health crisis assessment team. Find your local service by looking online at or phoning Healthline 0800 611 116.

What are some examples of self-harm?

People can harm themselves by:

  • cutting or burning their skin, especially on their wrists, arms and legs
  • punching or hitting themselves
  • banging their head against a wall
  • pinching, biting or scratching at their skin
  • pulling out their hair or eyelashes
  • eating or drinking something poisonous
  • overdosing on drugs or medication – enough to hurt but not risk killing themselves
  • sniffing harmful substances.

Why do people self-harm?

There are underlying reasons for someone self-harming. They may be dealing with difficult life issues, such as childhood abuse or emotional neglect, bullying or exam pressures at school, identity issues around their sexuality, or other challenging life situations.

Someone who is self-harming may also be coping with mental illness, such as anxiety or depression.

What are the signs of self-harm?

People often try to keep self-harm a secret because they feel ashamed of what they are doing. For example, if they are cutting themselves, they might wear long sleeves.

If you think someone you care about is self-harming, look out for these signs:

  • unexplained cuts or bruises, or cigarette burns on places such as their wrists, arms, thighs or chest
  • keeping themselves fully covered, even when it is hot
  • having a low mood, being tearful or lacking motivation or interest in doing anything
  • talking about themselves in a negative way
  • saying they want to punish themselves for something
  • getting withdrawn and not speaking to other people
  • blaming themselves for any problems or thinking they're not good enough for something
  • signs they have been pulling out their hair or eyelashes
  • signs of misusing alcohol, drugs or medication.

What kind of treatment is there for self-harm?

You can get help for self-harm through support groups and psychological counselling or therapy. There are people with specialised knowledge of how to help someone who self-harms. They will be supportive and take your concerns seriously. They can help you to stop self-harming and deal with the difficulties in your life in ways that don’t hurt you.

You can contact your doctor to help you work out what kind of help would suit you best.

If you are self-harming because of sexual abuse or a sexual assault, ACC will subsidise (reduce the cost of) your counselling or therapy.

How can I help myself if I am self-harming?

The best thing you can do to help yourself is to tell someone you trust: a friend, family member or your doctor, or phone one of the helplines listed under Support. Don’t cope with this on your own. Remember: there is help and there is hope.
