Alzheimers Manawatu manager Donna Hedley agreed, saying resources were declining, while dementia rates were on the rise.
After funding cuts last year, she said the organisation had to work a lot harder to try and achieve their goals.
"Obviously with limited resources, our challenge is how to continue to meet demand," she said.
"Grant figures are dropping and we've had some funding decreases from the DHB last year."
Hall said that, conversely, providing better support to people with dementia early will actually result in significant savings.
Research commissioned by Alzheimers NZ in 2008 found that delaying entry to residential care by just three months would have resulted in $32 million of savings that year.
"These costs are not just carried by the public health system, but also in productivity losses for carers who may have to give up or reduce paid employment to look after their partner," Hall said.
Hedley said initiatives in Horowhenua, including a dementia day-respite programme in Levin's Masonic Hall, had seen increasing numbers of clients.
There was also a dementia adviser, who had become a valuable resource for affected people and their families.
Despite this, she said there may be people in the community who suspect the early symptoms of dementia in themselves, or in a loved one, and who may not know how to reach out for support.
"If they are concerned, they can always get information from us, and it can be anonymous," she said.
"In Levin there are significant challenges already. Access to local GPs has been a challenge [for some time] and I think is generalised knowledge."
She said family members of people with dementia symptoms should remember that the GP may be unaware, as people can present quite normally in appointments.
