怀特玛塔港（英语：Waitemata Harbour）是奥克兰的主入海口，所以有时也被称作奥克兰港。尽管港口几乎环绕全市，但全市还是几乎被奥克兰海港大桥纵横交错地连接着。港口北面和东面皆被奥克兰地峡包围，南面则与马努考港的浅水区相接。 港口占地70平方英里，连接奥克兰码头和奥克兰海滨，沟通太平洋和豪拉基湾，同时受到北面的北岛城、朗伊托托岛和怀赫科岛的保护，使得怀特玛特成为一个优良的避风港。 “怀特玛塔”是毛利语。最早来到奥克兰的毛利人，当在港口看到闪闪透亮的海水，就把港口描述成“如宝石般闪烁的海洋”，取名怀特玛塔。

Waitematā Harbour is the main access by sea to Auckland, New Zealand. For this reason it is often referred to as Auckland Harbour and is crossed by the Auckland Harbour Bridge, despite the fact that it is one of two harbours surrounding the city. The Waitematā forms the north and east coasts of the Auckland isthmus. It is matched on the south by the shallower waters of Manukau Harbour.
