Campaigners are calling for better understanding of dementia as new figures reveal the number of cases could triple in New Zealand by 2050.
Bupa and Alzheimer's New Zealand said dementia already affected about 50,000 people, and the number would only rise as the population grew.
Catherine Hall, Alzheimer's New Zealand executive director, said it was "critical that we are well positioned to meet the needs of the growing number of people affected by dementia".
"Although there is currently no cure, there is help available to help people affected by dementia," she said.
"In 2012 we launched the Alzheimer's NZ We Can Help campaign to encourage people to see their doctor so they can get they help they need, and to build public understanding of dementia, [and] awareness of the services and support available to people affected by dementia.
