The Manukau Harbour is one of the most extensive inlets on the west coast of New Zealand, with a water area of 394 square kilometres. However, navigation is restricted to several clearly defined channels due to a number of factors. A large part of the harbour consists of tidal sand bars, a curving sand bar is situated several miles offshore across the harbour entrance, and the harbour entrance is extremely narrow.

The sinking of the HMS //Orpheus// on 7 February 1863 was the worst maritime disaster in New Zealand history and a dramatic event in this Port’s history, highlighting the limitations of the Port of Onehunga. The 1,700-tonne steam corvette hit the middle bank, the Manukau Bar, at 1.30pm. By 9pm the mast, where most of the crew had taken refuge, went down; only 70 of 250 passengers survived.

Every 12 hours the sand bars in the Manukau Harbour move

Seems that they have tired things and have made improvements (even though they shifted from Waitematea out to Manukau Harbour) spend alot of time and money, It proves that they are cleaning out the water 5/6 times before releasing it into the Harbour.
