Cure Kids began life as the Child Health Research Foundation in 1975.
Chief executive Vicki Lee said its founders, who were from the Rotary organisation, wanted to do something to bring down New Zealand's infant mortality rate, which at the time was high for a developed country.
It has grown to become a significant funder of research into stillbirth, cancer, rheumatic heart disease and numerous other conditions that afflict children.
Last year it reported total income of $10.6 million, of which 8.9 per cent was spent on administration.
