A social scientist who found a link between housing conditions and health has claimed the top award at the Prime Minister's Science Prizes this year.
The top prize of $500,000 went to Philipa Howden-Chapman and her 28-member team at Otago University in Wellington.
Their work included large-scale community trials involving about 10,000 people to demonstrate the effectiveness of initiatives such as retrofitting insulation on health.
