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.

Our Team in Action: Emergency Flood Response at Hamilton Police Station

Last week, our CST Group team was called urgently to the Hamilton Police Station after a council pipe burst and caused extensive flooding throughout the basement.

Our crews used our specialist vacuum trucks and equipment to quickly and safely remove the floodwater, bringing the affected area back under control.

It’s exactly the kind of job our Flooding & Emergency Spill Response service is built for.

With an experienced crew available 24/7, and a fleet of vacuum trucks and hydrovac units ready to go, we can respond quickly when flooding, spills or liquid waste emergencies threaten to disrupt a site.

For commercial, industrial and public facilities, a fast response can make a big difference in limiting disruption and preventing further damage.

If you have flooding or a spill that needs urgent attention, give CST Group a call - we’re Here to Help.

MEET MATT 👋

If you’ve had one of the CST Group trucks turn up on site, there’s a good chance you’ve met Matt.

Matt has been with CST Group for almost 9 years and is one of the guys out there doing the mahi, meeting customers and getting the job done every day.

Let's learn a bit more about our amazing Matt!

FAVOURITE PART OF THE JOB
Being out and about, meeting people and never knowing exactly what the day will bring. No two days are the same, and over the years he’s made some great mates along the way.

SOMETHING CUSTOMERS MIGHT NOT KNOW
You can’t always completely empty a tank if there’s a high water table around it. Take too much weight out of the tank and there’s a risk it can actually lift or “pop” out of the ground. A good reminder that there’s often a bit more to these jobs than simply turning up and pumping a tank out!

BIG ACHIEVEMENT
Matt got his Class 4 licence a few years ago, helping him take on even more of the work happening out in the field.

AROUND THE YARD
Matt is known for always being up for a good yarn - whether that’s with the team or customers out on site.

OUTSIDE OF WORK
Weekends are usually a mix of hunting, fishing, watching the kids’ sport and spending time with family. One family tradition Matt values is getting everyone together for dinner once a month. And if you’re looking for him on a quiet Sunday morning, Robert Harris in Cambridge is a pretty good place to start. ☕

FUN FACT
Matt was born in England and moved to New Zealand when he was three.

WHAT’S PLAYING IN THE TRUCK?
Depends on the day - ZM, The Rock or whatever Spotify playlist is doing the job.

BUCKET LIST
A year-long tour around the Northern Hemisphere……and a hunting trip in the South Island. 🎯

Next time you see Matt out and about, make sure you say g’day, there’s a very good chance he’ll be up for a yarn.

Congratulations to our July review winner, Diane Millow!

Diane left us this lovely review:

“Highly recommend this Cambridge company as we've been using them for many years. They are prompt, efficient and do a discount on more than one septic tank empty. They do a thorough job and always offer helpful advice.”

Thanks so much, Diane! We really appreciate the kind words, and your ongoing support over the years. 💛

And a special shout-out to the lovely Clara from our accounts team for being a good sport and helping us with the winner video. After asking around a few of the team and getting a few very quick “not me!” responses 😂 , Clara kindly stepped up to the camera.

It turns out plenty of the CST Group team are much happier working behind the scenes than starring in front of the lens!

But if there’s someone from the team you’d like to see make a cameo, let us know in the comments - we’ll see what we can do to convince them to get in front of the camera! 🤞

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.

INVESTING IN OUR PEOPLE IS HOW WE BUILD A STRONGER BUSINESS.

Yesterday, Kylee, Clara and Anna from the CST Group office team attended the Ownership Mindset Workshop hosted by UBT.

The workshop is designed to empower individuals to think like owners, take greater accountability, and create value every day. It's about building confidence, initiative, and a mindset that drives positive outcomes, for both the individual and the business.

At CST Group, we believe that great businesses are built by great people. That's why we're committed to continually investing in the development of our team, not just to build skills, but to empower every person to make decisions, solve problems, and contribute to the ongoing growth of our business and the success of our clients.

When our people grow, our business grows.

The ladies thoroughly enjoyed the workshop, with the experienced lineup of presenters sharing practical, real-life insights that challenged their thinking and reinforced the value of an ownership mindset. It was also a great opportunity to network with other businesses, exchange ideas, and learn from the experiences of like-minded professionals.

A big thank you to UBT for delivering such an engaging and valuable workshop. We're excited to put these learnings into action!

MEET ROSS BREWER

If you’ve called, or worked with CST Group recently, there’s a good chance you’ve already dealt with Ross.

As General Manager at CST Group, Ross plays a key role in keeping the business moving across our Liquid Waste, Industrial, Water, and Factory divisions. From supporting the team and working with clients, through to planning jobs, improving systems, and helping drive the business forward, Ross is involved across a wide range of day-to-day operations.

At CST Group there is plenty going on, and Ross is usually right in the middle of it.

What he enjoys most about the job is working with a great team, solving problems for customers, and helping CST Group continue to grow while staying true to its values.

At CST Group, we’re here to help, and Ross is a big part of making sure that happens.

FAVOURITE PART OF THE BUSINESS
Ross enjoys the variety. No two days are the same, “there is normally something crappy to sort out” 😊.

OUTSIDE OF WORK
Ross enjoys a good road trip, preferably down a route not travelled before, and spending time with his wife and 3 boys when he’s not working in the business.

DREAM ADVENTURE
A proper family holiday, somewhere warm (a fire at the beach), with a little phone reception just in case it's urgent😊.

FUN FACT
Ross joined CST Group after 17 years working in other teams and has helped grow the business into what it is today.

Give Ross a shout next time you’re in the office, out on site, or speaking with the CST Group team. He’s always happy to help find a practical solution.
