The Transport Agency says a new expressway in the Kapiti Coast will directly affect sacred Maori land and require the demolition of 16 homes.
The agency says it had to decide between a western and eastern option for the expressway. It chose the western route which will require the demolition of 13 fewer houses.
Regional director Jenny Chetwynd says a Maori burial ground (urupa) is in the path of the proposed expressway.
Ms Chetwynd says the agency also decided against going through Queen Elizabeth Park.
This will require the demolition of more houses, but will avoid cutting off 100 houses in the area from the rest of the community.
A group opposed to the expressway says the route will divide the community.
