An afternoon tea and donated goods from businesses in the Aramoho Shopping Centre helped the Aramoho Women's Institute raise $322 for Kidney Kids.
And this week a builder from Wellington donated $100 to the cause, which brought the total to $422.
Institute president June Swann said she was grateful toAramoho Four Square, Essence Catering's carrot cakes, Stimpson's Pharmacy, Charisma Hairstylists and Aramoho Mags and Lotto, who had all donated goods for the afternoon tea raffle.
Mrs Swann said 18 members turned up and paid $5 to watch a musical DVD and have afternoon tea.
In June, the Aramoho institute held another afternoon tea and raised $150.
The New Zealand Federation of Women's Institute (NZFWI) had given each of the 48 federations throughout New Zealand $10 worth of teabags and coffee to start a "snowball raffle".
It was up to the institutes how they raised the funds from the start-up tea and coffee.
In the 2012-2013 year, the NZFWI made the Kidney Kids ward in Auckland its fundraising focus.
The NZFWI considered it a drab place for the under-2 year-old children, with not enough equipment to go around and some of the youngsters having to be placed in with adults for treatment.
To date, the federation throughout the country have raised $9417 through their snowball raffles.
At the NZFWI annual meeting in June, the organisation presented a $15,000 cheque to Kidney Kids chief executive Paul Norfolk.
They hope to double that by June 2013.
Wanganui has seven institutes in its federation, with Aramoho being the largest with 37 members.
