Maungakotukutuku is a rural locality on the Kapiti Coast of New Zealand's North Island. It is located inland, behind Paraparaumu and Raumati, and the 2001 New Zealand Census of Population and Dwellings gave its population as 621 people, an increase of 38.9% or 174 people since the 1996 census.
The Maungakotukutuku Stream and Wharemauku Stream both have their headwaters in the Maungakotukutuku area. Maungakotukutuku Valley has been considered as a possible site for a dam to boost the Kapiti Coast's water supply. The hilly areas, often called "the Maungatooks" by locals, have tracks popular with trampers, mountain and dirt bikers, and horse riders.
