A shallow lake on a sandy plain two kilometres to the west of Levin and five kilometres from the coast.
Punahau was once surrounded by podocarp forest as the centre of a rich wetland ecosystem. Today the trees are gone and the wetland has been substantially drained. The lake is owned by the Māori Muaūpoko iwi, who, with the help of the Horowhenua Lake Trust, are actively attempting to restore the wetland system (that also contains the smaller Waiwiri - Lake Papaitonga) to its former state as a conservation area.
A large variety of bird life visits the lake - a great place to feed the ducks with the littlies. It is a peaceful spot with play equipment and large grassed areas.
No power boats are allowed and the lake is not suitable for swimming. Dogs only allowed in designated Agility/Obedience Club areas.
