If your land falls in an ideal area for a Waitemata-to-Manukau harbour canal, it may be confiscated.
Across Auckland. Using the Auckland and Manukau Canal Act, 1908, the Auckland Harbour Board can “purchase or take or otherwise acquire” land for the purpose of constructing a harbour-to-harbour canal.
It can take the land “from time to time, either within or without the limits of its jurisdiction”.
