Labour says a Families Commissioner must resign after she confirmed her plans to seek nomination for the National Party.
Commissioner Parmjeet Parmar revealed today that she wanted to represent National in the Hunua seat at the general election in September.
Her announcement followed questions by Labour last week about her political connections.
Labour's associate social development spokesman Rajen Prasad criticised Dr Parmar in a select committee for campaigning for National while holding an advocacy role.
He showed a picture to the committee of her wearing a National Party rosette while being photographed with Prime Minister John Key at the Pasifika Festival.
