HI WEST COAST! WHO’S COMING TO AGFEST? 🎉🚜

Got a milk quality headache you can’t shake? A high cell count, a grade, or a vat that won’t cool down? Bring your questions to the Terravest Troubleshooting tent at site 34! 🔍

For the first time, all three of our brands are together at an event, so we can tackle any milk quality problem from every angle:

🧴 Deosan: The clean freaks. Cell counts, teat health and shed hygiene sorted.
🧊 Cryvex: The cool ones (literally). Cooling and electrical gremlins found and fixed (previously known as DTS).
📡 Agora: The techy ones. Vat data that shows exactly where things are going wrong or right!

From teat to tanker, we’ve got you covered 💪

And the best bit... swing by and you could WIN a $2,500 trip to Queenstown!

Keeley didn't switch teat sprays to fix his SCC. He switched to save his hands.

The iodine spray he'd been using on his 300-cow Rotorua herd is acidic by nature, and handling the mix every milking was leaving him with painful blisters. So he made the move to Deosan Teat X.

The blisters stopped almost immediately. Then something he didn't expect happened: his SCC, which was already sitting at an acceptable level, started coming down.

Ten years on, Keeley has kept his SCC low, season after season, with last season coming in at an excellent 20,000.

"Acceptable" SCC doesn't always mean there's no more room to improve.

Think your SCC has more to give? Talk to your local Deosan rep about making the switch to Teat X.

One of our customers snapped this cracker while our team was on farm bomb washing his plant. Can't beat a good dose of rural NZ at the end of a long day.

We're grateful every day for the dairy industry and the farmers who back us.

Cheers for the share Ben! 😎

A quick word on our free promotional bomb washes and what's included, since it's come up a bit lately.

A free bomb wash is our way of helping customers out during one of the busiest times of the year, a free pre-season clean of your vat and lines, no cost to you. It's a gesture to lighten your load heading into the season, not a full maintenance service. We'd genuinely love to throw in a free full maintenance service too, but like you, this is our busiest stretch as well, and our team's time still needs to be paid for.

That's why tap and valve maintenance, pulling things apart, checking wear, replacing seals, sits outside the wash itself. It's a different job with different time and tools involved, so it gets handled separately.

While we take care of the wash, we're counting on you to sort the rest, whether that's a DIY job, a call to your vat manufacturer, or a call to a qualified technician. Responsibility for that sits with you or your dairy company depending on who owns the vat, so worth a quick check if you're not sure. We’re happy to recommend some detergents to help 😉

Honestly, pulling apart your taps each season and replacing seals is a great habit for peace of mind, and we're always happy to point you toward parts or the right person to call, even when the job itself is outside our bomb wash visit.

Wishing you all a great calving season ahead! And if you're reading this and fancy a free bomb wash, sing out, we'll see if we can slot you in (area depending).

We need to talk about vats. We know, they aren't as interesting as cows ❤️ - but they are pretty important. If your vat hasn't been touched since dry off, now's the time to start thinking about it.

Deosan's range covers the full cleaning cycle - alkali to acid. NZ-made, manufactured to meet NZ dairy hygiene regulations and best practice guidelines, and proven in sheds across the country.

Not sure where to start? Give us a call and we'll get your vat up to scratch before calving. 🐄

Calling all ag graduates, we're looking for you! 👍️

Terravest Group is kicking off a Graduate Pathway Programme and we're looking for motivated graduates to join us for the 2026/27 season.

We're the team behind Cryvex (refrigeration), Agora (real-time vat monitoring), and Deosan (dairy hygiene) - three businesses that work right at the heart of the NZ dairy chain.

This isn't a desk job. You'll be out on farms, learning from the ground up across all three businesses, working alongside technicians, compliance teams, and commercial reps - and building a career that goes somewhere real.

One of our current team members, Seb, started as a two-month work experience placement. He's now full-time across Agora and Deosan. That says it all, really.

✅ 24-month structured programme
✅ Real technical training + industry certifications
✅ Farming background preferred
✅ Based in New Zealand

You take ownership of a real portfolio and build your career with our full support - and for the right people, international opportunities in Australia, Southeast Asia, and beyond.

We'd love to hear from people with experience in:

🔧 Milking machinery

⚡ Electrical (rural & agricultural)

❄️ Refrigeration

🌱 Farming & agriculture

We're after people with real NZ farming experience who are technically switched on, solutions-first, and don't wait to be told what needs doing.

After a season of our customers opening their gates, their sheds and their homes to us - it was fantastic to open the doors to our brand new office to some of our favourite people. Good food, excellent company, and a round of golf to top it off.

Next year will be bigger and better, because who doesn't love a good shed party?

You know Deosan. Now meet what we've been building. 👋

Introducing Terravest.

Deosan is the heart that Terravest was built around - a NZ-owned family business that's now brought together dairy hygiene, smart farm data, and milk cooling all under one roof:

🌿 Deosan - NZ's trusted dairy hygiene experts with decades of on-farm experience.

❄️ DTS Refrigeration - a long-standing name in NZ dairy milk cooling, now proudly Kiwi owned and operated.

📡 Agora - NZ's first wireless IoT vat telemetry provider, delivering real-time on-farm data.

Same team. Same faces. Same no-nonsense people you've always known - now playing a much bigger role for 6,000 NZ dairy farmers and nearly $11 billion in milksolids.

We're still Deosan. Always will be. And we're pretty excited about what comes next. 🌿
