  • Depression is extremely common in New Zealand, with 1 in 6 people experiencing it at some point during their lifetime.
  • Depression can affect people at any age, from children through to older adults. Women are more likely to be diagnosed with depression than men. It’s not clear whether this is because depression affects females more, or if males are less likely to seek help.
  • Symptoms range in severity, from feeling generally low to thoughts of self-harm or suicide.
  • Treatments include lifestyle changes, psychological therapy and medications – often a combination of different treatments is used.
  • Depression is not a sign of weakness. It’s a treatable illness.
  • If you or someone you know is experiencing depression, you should seek help from your GP or healthcare professional.
