The Government is to spend $250,000 on a national media campaign to help raise awareness about dementia.
Health Minister Tony Ryall said that as more people live longer, the number with dementia will also grow.
He said on Tuesday that finding out you that have dementia is dificult and the sooner people have the information the sooner they and their family can get support.
The Alzheimer's New Zealand support group will manage the campaign.
It will involve television and magazine advertising aimed at reducing the stigma and encouraging people to see a doctor if they or others notice signs of the condition.
