"I'm keen to look at why Maori are reluctant to be organ donors because of cultural aspects. I'll be forever grateful to BayTrust for these scholarships which have enabled me to pursue this pathway through tertiary study."

It was named after the late Ray Dillon, a former chairman of the Trust Bank Bay of Plenty board and former Tauranga mayor. His wife - former Tauranga deputy mayor and BayTrust chairwoman, Mary Dillon - said she had no idea the scholarship would grow into the significant programme it was today.
