New Plymouth's Mayor is challenging those opposing the formation of a Maori Ward in the city, to front up to a forum next week.

The forum will have experts on Maori representation in local government, and will allow the public to ask questions.

The formation of a controversial Maori Ward in New Plymouth, is dependent on the outcome of the referendum starting next week.

Mayor Andrew Judd says this is an opportunity for those opposed to the wards to alleviate their fears.
