M2PP -Expressway pollution of Kapiti Waterway -The Full Story


Welcome to the Midnight Collective Broadsheet 120
Actively supporting NZ’s endangered wetland birds

Those who have been regular followers of this environmental story will be familiar with the watch we have been keeping on the levels of pollution entering our local waterway –the Wharemauku- through the destruction of a rare dune lake here at Raumati Beach.  This controversy has recently hit the headlines in a local paper.


The safety of our waterways is in the hands of the Greater Wellington Regional Council (GWRC)  and they have responded to the discolouration in the story above. Regional Council competence is coming under fire after an outbreak of severe enteritus over recent weeks infected 5000 in Havelock North and made international headlines. It has been provisionally traced through the town water supply to local dairy farming.

Our local pollution story was stimulated by a graphic image of the polluted Wharemauku taken by Jamie Guertjiens, but the pollution isn't new and here are some more images we have taken over the last two years.

Here is why we don’t  believe the WGRC.

We have been watching this stream for five years now, and these levels began to rise  sharply when expressway excavation started, while the red colouration began appearing when locally quarried rock was trucked to the site.

The GWRC is correct in locating the pollution source as ‘natural’ but it is the level, density and constant flow of the pollution which are at issue. Discolouration occurs after rain but it previously cleared within two or three days. It still does this in drains that are not linked to the expressway. The GWRC as the guardian of our waterways, should know this. Nor does it take any initiative to follow the pollution back to its source in Drain 7.
Drain 7 
We laid a complaint with them last year over two issues – the pumping of polluted water from the NZTA excavations into the Wharemauku below pollution monitors. These were set up at the directive of the Board of Inquiry that issued consents for this work which could close the site down if pollution reached unacceptable levels. We also provided evidence that the pollution  monitors themselves had been out of commission for months on end.

We got a reply similar to the one supplied to the Kapiti News, until we showed them photographs of the NZTA pumps at work. The GWRC advised that the NZTA didn’t have a consent to discharge into the Wharemauku, so they then got off their laptops and undertook a more serious investigation. The result determined that under National Government regulation, the NZTA could do pretty much whatever it wanted. 

Why didn’t the GWRC know this? 

What the NZTA further advised however was that it had workers with hand monitors stationed on the banks of the stream while this pumping had been going on. We had never seen this, though what we had seen were pumps hard at work early Sunday morning with no-one around. But we had to take them at their word until this years autumn rains set in. The NZTA had denied all along that there was a dune lake down here and finding that there was one and that their excavations had enlarged it, they now opened a permanent drain into Drain 7. Here it is...

This empties into the Wharemauku  below the monitors and is the primary source of the pollution.

One indicator of its seriousness has been that local ducks are now avoiding these lower reaches. Marine life in this rich and delicately balanced waterway, must be similarly affected.

Other waterways that appear to be impacted by the disturbance of this 1000 year old swamp are Andrews Pond and Ratanui Road though our readers will be interested to learn that Forest and Bird are keeping a close watch on these developments.

Track we were listening to while posting this – Slim Whitman A Fool Such as I 
Now and then there's a fool such as I am over you
You taught me how-ow to love and now-ow
Now you say we're through

Bob Dylan ran a version of this off through his peerlessly glass papered throat and nose, though nothing  can compare with this operatic tenor that came boating out of American country and then western  music through the fifties… Susie cant abide this so we're sneaking it in unbeknownst.
