Matiatia is a location at the western end of Waiheke Island, in New Zealand's Hauraki Gulf.[1] The name is used for both a valley and its surrounding hills, with the valley stretching down to a foreshore and wharf on the gulf.[1] Matiatia is known as "The Gateway to Waiheke Island".[1]
The Māori language name mātiatia is shared with a type of beach grass, now rare, which was known to grow at the gateway.[2][3]
