On the other side of the world, far, far away, some very important assembling is well underway

A bit like a jigsaw puzzle, piece by piece our Tunnel Boring Machine (TBM) is being put together in Germany by Herrenknecht, one of world’s premier TBM manufacturers. Once fully assembled it will be 165m in length - a bit more than one and half rugby fields - and be loaded onto a boat bound for Auckland. From there, it's certainly no holiday for our TBM, it will be put to good use on New Zealand’s largest wastewater tunnel, digging up to 110 metres underground from the Manukau Harbour to Grey Lynn. Check out this time-lapse footage from Germany of the TBM puzzle taking shape.

Not just your ordinary shells

Try saying this sentence at speed three times in a row: “Shayne sells seashells by the seashore.” Blimey, that’s a mouthful! To be fair, Shayne isn’t selling seashells, but he is digging up delightful discoveries. Shells dating back 3-4 million years have been unearthed by our Central Interceptor team during their work at our Māngere site. It's definitely a once in a lifetime discovery. Check out the One News story and find out what executive programme director Shayne Cunis thinks of these special super-sized shells:

Underground construction phase underway

Yesterday, guests including Auckland Mayor Phil Goff and councillors engaged in a ceremonial dig to celebrate the Central Interceptor officially entering its underground construction phase. The dig, also known as a sod turning, took place at our Māngere pump station site. The shaft at Māngere is being constructed by our impressive hydrofraise machine that will go 50-metres underground to create the deepest diaphragm wall in New Zealand history.

Following his involvement in the ceremonial dig, Mayor Goff said, "The Central Interceptor is one of the most significant infrastructure projects in Auckland. Together with Watercare and Auckland Council’s other projects in Auckland’s western isthmus, it will substantially improve water quality and reduce wastewater overflows by at least 80 per cent, while providing for population growth in the city.”

Engaging the community at Keith Hay Park

This is the first in our series of video newsletters about the Central Interceptor project. Each month we’ll be showcasing an aspect of the work being carried out in building New Zealand’s largest wastewater tunnel. Our first video is all about community engagement. On Saturday, our team and contractor Ghella Abergeldie Joint Venture chatted with locals about the work soon to get underway at Keith Hay Park.

Preserving Oakley Creek’s eel habitat

Before we started work on the bridge over the stream, we collected 114 eels (tuna) living in this section of Oakley Creek. To keep them safe, we temporarily released them downstream. With the bridge installed, we reinstated the original water flows; the eels can swim back upstream to return to their local hiding spots and feeding grounds.
