The number of people with dementia is much higher than previously estimated, according to a study tabled in Parliament on Tuesday.
The report into dementia's economic impact shows that slightly more than 40,000 New Zealanders suffer from dementia and that the number is set almost to double by 2026.
Alzheimer's New Zealand says there is a crisis facing people looking after dementia sufferers and the Government needs to act now.
Chairman Bryan Bang says most care is being provided in the community, which has a huge impact on families and carers.
Dr Bang says there needs to be appropriate funding available to support families who are caring for sufferers.
