Pollution levels rising in the Wharemauku - 3 -The destruction of a New Zealand wetland


Welcome to the Midnight Collective Broadsheet 96
Actively supporting NZ’s endangered wetland birds


Bonjour, once again to our French friends, who may or may not be rugby people, though you read it here first – the NZ-French matchup at Cardiff Arms…And this is to say that everyone down in this hemisphere is very very nervous about what you guys are going to pull out of your cockaded tricornes this year. 

Though now we can get back to our story on pollution in the Wharemauku.

Polluted lower reaches of the Wharemauku
No-one is talking about this pollution, including the agency that should be monitoring it, the Greater Wellington Regional Council (GWRC) – our waterway pollutant watchdog. So we have had to assemble our own evidential record and publish it here. And bear in mind while we go through this, that the NZTA has denied all along, through the Board of Inquiry, that there ever was a wetland here.

Expressway bridge site Raumati beach

What we are going to do is try and track what the NZTA has been doing regarding pumping polluted water into Drain 7 and a good place to start is with water they are now pumping from the northern site of the bridge construction. They have dug a stream diversion around the bridge site and are lifting water from this  across the Wharemauku, into the area where the dune lake used to be.

Over the Wharemauku and into the destroyed dune lake
This water collected in the excavated sand dunes on the north  side of the bridge construction. It had been left to settle, so was  relatively clear; clear enough perhaps, for it to have been pumped out into the Wharemauku.  They aren’t doing this however but pumping it back into the site where the dune lake used to be and which they have previously gone to a great deal of trouble to drain. The water in the destroyed lake however, is now filling back to the levels it had reached, before it was drained in August. And it is that draining drama we are now going to focus on. 

This new pumping activity however, has been useful in revealing the NZTA’s draining methodology. The pump was observed around 7am on a Sunday morning (The site is shut down on a Sunday though work usually begins at 7.30 during the week). It was unattended and had been left working through Saturday night, though there are residential houses close by.
Hard at it. Draining the dune lake early August 
It was back in August that the NZTA first began draining what was left of the dune lake. We have noted how the dune lake areas had expanded once the NZTA began levelling the area and carting sand from the surrounding dune lands onto the expressway –building up its escarpment. Despite being sat in a swamp basin the dune lake always ran clean, but with the disturbance of the peat the water on this site has became polluted.
Drainage channels to hidden drain.  
The engineers then began excavating channels between these areas connecting them up and building a passageway that led back to an inaccessible  hidden drain, that channelled water (underground) into Drain 7 and thence the wharemauku.
Sump spilling polluted water into hidden drain
This was easy to track if you knew what you were looking for; but who would think the NZTA would begin pumping water into Drain 7 through such a circuitous farrago. Why go to all that trouble when they might simply spill it straight into the wharemauku. There might be many reasons for them to do this, though the one that immediately springs to conservation mind is that they needed to release this pollutant water, below the monitors set up in the wharemauku to detect pollution leaking from the site. Why? Because the site could be shut down if they reached prescribed levels.
Compressor draining polluted water early August
We gathered incontrovertible evidence that that was exactly what the NZTA had done. And took it to our environmental watchdog – the GWRC…
Pollution in Drain 7 early August
We have  a lot of time for the GWRC, because it's working in an environmental no-mans-land set up by the Board of Inquiry. This Board has effectively overruled the RMA leaving the NZTA to work without environmental legislative oversight so they appear to be  making up the rules as they go along. And these rules are based on expediency. Helping this is the fact that the GWRC have formed a team to work in close liaison with the NZTA to fast track environmental consent processes as they arise. As we saw in the financial crisis of 2008 however once Business and its auditors chum up, expect trouble.

What we didn’t expect however was that despite this cosy relationship, the GWRC had no knowledge of what was going on at this excavation site.

We have taken enough of your time  in this post however, and will continue this story in our next one.

Though here’s an update on our dabchick chicks who are thriving down at the Waikanae estuary. Which provides a timely reminder of why we’re out here, undertaking  this investigative toil.

One noticeably bigger than the other.  Heres  the largest.
Track we were listening to while posting this… we’re on a Carter Family binge so its  I'm  thinking tonight of my Blue Eyes'   

'Twould been better for us both had we never
In this wide and wicked world had never met,
But the pleasure we both seemed to gather
I'm sure, love, I'll never forget

Oh, I'm thinking tonight of my blue eyes
Who is sailing far over the sea
I'm thinking tonight of my blue eyes
And I wonder if he ever thinks of me


The women were the heart and soul of this band though it was AP who collected the songs, a fascinating toil, that managed to archive songs that stretched back through the 19th century and then some.   What it revealed amongst many other things was  how music was universally present in those lives, not simply in the church congregations on Sunday's, but in the kitchens and wash houses of the local people.  They made music for themselves whereas today (sigh) we spend our time listening to others make it.
