Mana Marina is a privately owned marina located at Paremata, on the shores of the Porirua Harbour near Wellington, New Zealand.

It is noted as the closest North Island marina to the Marlborough Sounds, with the entrance to Queen Charlotte Sound situated approximately 18 nautical miles to the west. The marina has 305 privately owned berths, including 29 available for rental.

All piers offer walk-on access from car parking, with direct power and water connections at each berth.

Mana Marina operates alongside the Mana Cruising Club, with the two organisations closely interdependent in the services they provide to the local boating community.
