Sleep-deprived residents living near the new Kapiti Expressway claim their human rights are being breached by night-time noise.
Bernie Randall, a member of the Paraparaumu/Raumati Community Board, has asked the Human Rights Commission to investigate their complaints.
"The home is literally the centre of the primary health system," he said.
"When homeowners experience disturbed sleep this causes stress, reduced work efficiency and poor life quality. For some it can affect their mental health."
Randall said there was a "glaring gap" between noise standards and acceptable noise levels for nearby homes.
