There is a Auckland Uni, study over many decades on the movement of the huge bank of black sand that has been going up the coast from taranaki . I understand movement has been going of for a few 100yrs.
From memory, as at a few yrs back the top edge is up around Port Waikato.
Which was re reason for sand encroaching some buildings not long back.
Yes currently its high seas and erosion digging at the houses, which is a different but parallel matter.
I cant rem when it gets to the Manukau, but was within my life time.
I have noticed a significant change in the banks /shallows on the inside of the waikato bar and narrowing of the main channel.
I do not know the actual reason why the Onehunga port was closed down...but as a kid we fished between the freighters off the wharf back then... late 50s to mid 60s. But Im sure there was a good economic reason for it, maybe including bar access etc.
Now throw in in the commonsense stuff you guys are saying about the bar...PhD s are far too often, to confirm what commonsence guys already know, at huge expense.
And I would not be surprised there are already a few research thesis on the bar floating around.
Throw in the huge black sand bank movement up the coast.
Throw in land access, which lets us not forget only recently this has been done at millions dollars of research and consultancy, and a bone of contention (like the Mill Rd project)
And they want to spend more millions going over the same damn stuff again???
Like duplicated the harbour bridge.crossing BS consultancy and waste public money of resent yrs.
We as rate payers and tax payer are actively watching our money go to consulting etc in numbers way out of proportion to any other government ... and then when or if every followed thru so often a total failure at the coal face.. everything from 'child poverty. law and enforcement to mental health, education.
This/ these is a very bad redirections of public funds from the coal face and pretty much helicoptering (with serious inflationary effects) of public funds into area of the economy where should not be going.
This is so wrong on so many faces.
