Fist tree out of my Nursary is a Karaka that accidentally sprouted in my Garden a few years ago. I planted it on this little ‘Island’ near Wai o Taiki Bay. Hopefully it helps hold it together.


Collecting nurdles for analysis
Collecting nurdles for analysis

Nurdles are pre-production microplastic pellets about the size of peas. Plastics companies melt them down to make stuff and sometimes they flush them away. Because they are Hydrophobic nasty chemicals like PCBs and DDE latch on to them, which would be cool but unforuntately they look like food and animals eat them and die. (details). I am collecting these ones in Pakuranga Creek to send to Japan for Analysis via

These Nurdles are likely from a local plastic manufacturing company. I will take some photos and let them know. Tru-Design

Update: I checked the storm water pipes that the plastics company uses and I found no Nurdles at all! They must be coming from somewhere else. Other storm water pipes in the area seem clean, there is something suspicious about the original outlet, there are too many different kinds of pallet for them to come from one spill.
No Nurdles

Pakuranga Creek

Trash Pile

Found this trash pile here whilst exploring the Pakuranga creek. Will let the Watercare Harbour Clean-Up Trust guys know about it and offer to help.

UPDATE We did, 11 Garbage bags of trash. It will be interesting to see what it looks like in a month or so to see how fast stuff is building up.

Watercare Harbour Clean-Up Trust

Heading out on the boat
Heading out on the boat

Today I went out on the Watercare Harbour Clean-Up Trust boat. We set off at a leisurely pace from downtown auckland in a rugged little boat (they are getting a new one next month) and headed under the Harbour Bridge out to the entrance to the Whau river. We kayaked over to Pollen Island and in just a few hours filled 9 bags with plastic before heading back. Amongst the expected bottles, bags and wrappers we also found:

  • One of those really old coke bottles with the removable black base
  • Lots of balls and kids toys
  • Fishing gear
  • x4 Syringes (Needles)
  • A geo-cache
  • x2 LPG Canisters

These guys have been doing this for 10 years and made a huge difference to the health of the Harbour. There is still a lot of historical waste to remove but we desperately need better source control. Interestingly they would prefer plastic to break down slower so it is easier to collect and remove. I left a lot of toxic little bits in the sand and rushes. I am looking forward to heading out again with Skipper Ben and hopefully the organiser Hayden Smith who are both awesome guys.


Map Walked
Where I have walked

In trying to understand why the estuary is so sick I have been exploring it, mostly on foot but some areas are easier to get to by Kayak.

Scaly contamination

I am used to seeing icky contaminated run off like this. From here. UPDATE: I think this is bubbling up from landfill (we have over 200 different sites around Auckland City). I have asked Auckland Council about it.

Bright Orange Mud

But this is just weird, it dries hard. Like the mud is covered in milky ice. I found it here.

Dumping. Another slip. The gravel below the high tide line.

I was looking for erosion sites when I saw Powerhouse Civil actually dumping material into Tamaki Estuary here. I will let Auckland Council know tomorrow.

UPDATE: (2 Weeks later) Rowan from By-Laws called me and is referring it to a pollution dept.
