The appointment of the head of an influential lobby group for the food industry to a health promotion agency is not a conflict of interest, Prime Minister John Key said this afternoon.
The new Health Promotion Agency board was announced on Friday, and included Food and Grocery Council chief executive Katherine Rich.
The council represented the $15 billion food and beverage industry and was an influential voice on food legislation and trade practices.
Mr Key said that the inclusion of Ms Rich - a former National Party MP - on the agency's board was appropriate.
"I'm comfortable that she'll be able to manage any conflict....It's important that a board has a range of different views."
