A day of adventure with the CST crew! 🏎️🏁

On Friday last week we headed to Rotorua for a fun team day out, kicking things off with some F1-style karting. It didn’t take long for a few competitive streaks to come out! Turns out we’ve got some aspiring racing drivers in the team!

Next up was the luge to keep the adventure going, followed by lunch together.

Our directors know it’s our people who make CST Group what it is, and they really value making time for the team. Days like this are a chance to recognise everyone’s hard work, enjoy each other’s company and share a few laughs outside the usual routine.

A big thanks to our directors for a fantastic day out, and to the whole crew for making it such a fun one! 🙌

Big ideas, clever technology and plenty of industry insights!

Yesterday, Barry, Edwin and Darryl headed along to International No-Dig Auckland 2026, getting amongst some of the latest innovations in trenchless technology and underground infrastructure.

It was a great opportunity to connect with others in the industry, check out new equipment and see how technology is continuing to change the way we tackle underground projects.

At CST Group, we're always keen to see what's new, share ideas and explore smarter, more efficient ways of getting the job done.

A big thanks to the organisers and the International Society for Trenchless Technology (ISTT) for bringing together so much industry knowledge and innovation under one roof!

Last Thursday, Ross, Darryl and Edwin headed across the ditch to Sydney to attend the Unlock AI Sydney Summit 2026!

At CST Group, we believe there's always room to improve. Whether it's refining our systems, finding more efficient ways of working or exploring new technology, we're constantly looking at how we can do things better and continue growing our business.

The summit gave the guys plenty of food for thought, with some great insights into how AI can support smarter business operations and future growth. Safe to say they returned with plenty of ideas and a few new things for the to-do list! 😄

We're looking forward to putting some of that knowledge into practice and seeing where it takes us. After all, a better business behind the scenes means an even better service for our customers.

A big thanks to UBT Australia and New Zealand for putting on such an insightful event!

CAMBRIDGE WATER DELIVERIES...

Different jobs. Same essential requirement: water where it’s needed.

A couple of recent jobs from the CST Water team show just how varied bulk water delivery can be.

In Cambridge, we’ve been filling water mains ready for new connections.

Out on the farm, it was a different story. A customer’s farm pump was playing up and couldn’t keep up with demand, so our team delivered water to help cover the shortfall while they got the issue sorted.

From infrastructure and construction work through to rural water supply, sometimes you simply need a large volume of water delivered to the right place.

That’s where CST Water comes in.

If you need bulk water delivered for a project, property or farm - get in touch with us now and we can get you a quote.

Backing local talent all the way to Chile!⚽

At CST Group, supporting our local community is something we’re proud to do, especially when it means helping someone chase a big dream. And there’s something extra special about being able to support people within the CST Group family.

We’re excited to sponsor Ellis Williams, the son of one of our CST Group team members, as he travels to Chile with the RH3 Ricky Herbert Academy of New Zealand to compete in an international football tournament.

Ellis will have the opportunity to test himself against some of the best young football teams from around the world - an incredible experience for a young player with big ambitions.

Everyone at CST Group is wishing him all the best for an incredible tournament! 💪

September’s review winner is… Brett Wallace! 🎉

Congratulations, Brett! There’s a Prezzy Card coming your way!

Brett chose CST Group for his septic tank clean and had these lovely words to share:

“CST are easy to deal with. Quick to respond to any questions and were available when we needed our septic tank cleaned. Service on the day was outstanding. There was a blockage that was dealt with quickly, as well as the tank being cleaned. We got quotes from multiple companies but chose CST due to the professional level of correspondence.”

Thanks, Brett! We’re proud to hear that our communication helped you choose CST, and that the team backed it up with outstanding service on the day. Taking care of our customers starts well before the truck arrives!

Is your septic tank due for a clean? Get in touch with our team to book it in. Whether you’re a returning customer or contacting us for the first time, we’re here to help.

A big thank you to everyone who leaves us a review. Your feedback recognises the hard work of our team and helps others feel confident choosing our family-owned business.

Congratulations to our latest review winner, Jeanne van Kuyk! 🎉

Your Prezzy Card is on its way!

Jeanne left us this lovely review:

“We had a leak in our farm concrete water tank, so we contacted CST Group as, due to the water pressure, the repair needed to be completed from the inside. The person who came out was friendly, helpful and professional, and did an excellent five-star job. I truly recommend CST Group to anyone out there.”

Thanks so much, Jeanne! We really appreciate you taking the time to leave such a great review. 💛

A little reminder, we clean water tanks and deliver water in bulk.

If you’d like to keep the water already in your tank, we can temporarily store it while the tank is cleaned and then return it afterwards. Or, if you prefer, we can deliver a fresh load of water once the clean is complete.

Thanks again to everyone who takes the time to leave us a review. Your feedback means a lot to our team and our family-owned business.

Darryl and Ross had a great day attending the Trade and Industrial Waste Forum last week.

It was a valuable opportunity to hear what’s happening across the trade waste industry around New Zealand, learn about some of the challenges and changes different regions are facing, and see how others are approaching them.

One of the highlights was meeting and connecting with a number of Trade Waste Officers from around NZ and having some really good conversations about what’s happening on the ground.

Always worthwhile getting out, sharing ideas, making connections, and bringing some new knowledge back to CST Group.

Good people. Good work. Good excuse for a BBQ & Some Beers. 🍻🔥

On Friday, we headed out to catch up with the awesome team at Phoenix Civil Limited and put on a BBQ to say thanks for their continued support and for being such a great team to work with.

Tanya took charge of the BBQ and absolutely nailed it, keeping the crew well fed while everyone enjoyed a proper catch-up.

We do a lot of work with Phoenix Civil, and having a trusted team to work alongside makes a real difference on every project. Good people, good communication and a strong working relationship go a long way.

Thanks for having us Phoenix Civil Limited - it's always great catching up with the crew, and we’re looking forward to plenty more projects together!

Looking forward to many more great projects together.
