A team of 21 hearing care coordinators set up screening, hearing-aid fitting and counseling during the two day clinics.
The foundation's Megan Baiocchi said on the first day they saw 710 people and 450 of those were fitted with hearing aids.
This continued into the final day she said, with adults and elderly the majority who required the hearing aids but some children were also fitted.
Matangi Tonga reports the foundation will provide free ongoing maintenance for the hearing aids.
