Statistics & data

The more people who understand stroke, its risks, warning signs, and treatment options, the more lives we can save and improve. Through awareness and action, we can reduce the impact of stroke, empower those affected, and create a healthier future for Aotearoa New Zealand.

• Stroke is a leading cause of adult disability in Aotearoa New Zealand.
• It is the second leading cause of death, with around 2000 people dying from stroke every year.
• At least 9,000 strokes and an unknown number of transient ischaemic attacks (TIAs) occur every year.
• ​​​1 in 4 people over age 25 will experience a stroke in their lifetime.
• About 89,000 people (2.1% of the population) are living with the effects of stroke today.

• In 2020, the annual economic cost of stroke was $1.1billion. This is projected to increase to $1.7billion by 2038.
• The number of strokes is forecast to increase by 40% between 2018 and 2028.​

• Stroke is not just a disease of the elderly. Up to 30% of strokes occur in people aged under 65.
• 60% of strokes among Māori and Pacific people occur at working age (15-64 years), compared with 20% for other ethnicities.

• Māori and Pacific people experience stroke on average 15 years earlier than European New Zealanders.
• ​​Māori experience worse post-stroke outcomes compared to non-Māori, largely due to systemic inequities that create barriers to accessing relevant healthcare and stroke education.
• People living rural and smaller centres experience worse post-stroke outcomes than those in urban centres.

• Most strokes are preventable. Up to 90% of strokes are linked to ten risk factors, including high blood pressure, physical inactivity, poor diet, and smoking – many of which can be controlled.
• High blood pressure is the number one controllable risk factor for stroke, and can be managed through regular checks, healthy living, and medication if needed.
• Atrial fibrillation (irregular heartbeat) increases stroke risk.
• Some risk factors, such as high salt levels in processed food and labelling policies, should be managed at government and policy level.

• A transient ischaemic attack (TIA) is a serious warning sign of a larger stroke to come.
• The F.A.S.T. acronym helps identify a stroke:
  • Face drooping
  • Arm weakness
  • Speech difficulties
  • Take action – Call 111 immediately if you notice these symptoms.
