The non-for-profit charity delivers medical care and education to several Pacific Islands.
Mr Mears said Marine Reach had recently purchased a new vessel, which was being fitted out so it could provide medical care.
He said the Marine Reach team worked with the various Pacific Island governments to bridge the gap between those who need health care and what the government can provide.
The ship-based operations have now expanded to include trucks, shipping containers and mobile clinics to provide humanitarian aid and relief to communities in well over 20 countries.
Mr Mears said the work they do would not be possible without donations from members of the public or through fundraisers by organisations such as Rotary.
"Rotary has been a great friend to us over the years and what they do for us has an enormous impact.
It allows us to carry on and do what we do best."
Mr Mears said the vessels would be based in Tauranga until about April when they will be going to Vanuatu and the Solomon Islands.
"There is quite a bit of need in both of those places and we will do our best to provide the care they need."
