He said last year the charity and volunteers made 1400 trips, taking people to specialist appointments - sometimes to Wellington - who could not otherwise go.
While lauding Wanganui residents' altruism, Mr Aitken felt the close-knit community meant people were more receptive to needs around the city. "People are actually more connected in rural communities so they tend to be more generous."
Registered charities' income in the Manawatu/Wanganui region has risen to $936million in the last 12 months, up from $607million five years ago - a 50 per cent increase.
However, charities' financial data has been self-reported and was not required to be audited.
Mr Aitken said his organisation was fortunate to have a consistent support base that regularly donated as it did not receive government funding.
The Wanganui branch services the Rangitikei and Waimarino areas, too.
Latest data show the number of health-sector charities in the Wanganui/Manawatu area has fallen, from 124 in 2010-2011 to 109 today, making up less than 7 per cent of charities in the region.
Nationwide charitable giving is up on previous years.
The latest figures released by Charities Services show income for registered charities is steadily increasing, up from $13.6billion in 2009-10 to almost $16.2billion, an increase of almost 20 per cent.
Those figures include government grants and contracts for delivering public services.
The education, training and research sector has been one of the big movers, increasing $1.5billion over the last five years, and taking 41.3 per cent of the nationwide charity income.
But losing its share of national income has been the health sector, which took more than 23 per cent in 2009-10 but now takes just 17.5 per cent.
Fundraising Institute chief executive James Austin said public donations were increasing.
"There's been a steady growth in giving. We're doing more."
Mr Austin said, despite New Zealanders' charitable giving, more could be done.
"I personally believe there's room for major growth.
"By no means is the generosity of New Zealanders over-saturated."
The increase in op shops and second-hand goods stores, like those run by Hospice New Zealand and the Salvation Army, enabled aid to be provided to more New Zealanders, Mr Austin said.
Store income went back into delivering services, and quality new or second-hand goods were more affordable for those who needed them, something Mr Austin described as a "double whammy".
Almost 1700 new registered charities have been established in New Zealand since 2009, pushing the current number to almost 27,000.
