Another wee dip in the crystal clear waters of the Maldives…… well not quite 🙄.
Our team undertake another contamination dive in water where you can’t see your hand in front of your face. Having a highly skilled team on site means that we can undertake tasks without being able to see it - simply by ‘feel’ and experience. That’s the difference in working with a team from Bay Underwater Services NZ Limited ✅✅✅
Top team doing top work ✅

Another unusual job as our team dived UNDER a pool floor 😳. This is an amazing design where the pool floor can be raised and lowered for different depths as necessary for different events/occasions.

⛑️👷🏼‍♂️⛑️Strict health and safety protocols were followed with the focus being on diver recovery.
Always something different in this industry!

BLUFF formally known as…… CAMPBELLTOWN!The area has been permanently occupied since the establishment of a whaling station in 1836. Originally named Campbelltown in 1856, the local moniker “Bluff” (in reference to the prominent 265m conical hill the township nestles beside) became the town’s official name in 1917. As one of the oldest European settlements in New Zealand, Bluff has a rich history and many interesting attractions. It also offers many wonderful short walks, both bush and coastal, that showcase the stunning scenery and views.

Turns out we are destined to be there 😂

Getting it done on Christmas Day 🎄⚓

While most of us were eating, drinking, and being merry with family and friends, these legends chose to put in the hard yards.

She’s cleaned, checked, and ready to get back to work ⚓️

Our dive support vessel has just completed her out-of-water maintenance, including a full clean and inspection. Keeping our vessels in top condition isn’t just about looks — it’s about performance, reliability, and safety on every job.

Now it’s time to get her back in the water and back to doing what she does best. At Bay Underwater Services, we take pride in keeping all our gear and vessels in tip-top shape so our team can deliver the highest standard of commercial diving services, every time.

Not every dive is about what you see — some are about what you don’t bring back with you.

Our team is heading into a contaminated diving operation, where the real work starts long before anyone enters the water. Detailed planning, strict procedures, and disciplined ex*****on are what keep our divers, clients, and environments safe.

From controlled entry and exit points to full decontamination processes, this type of work demands a calm, methodical approach and a crew that understands there’s no room for shortcuts. It’s about doing the job right — every step, every time.

This is where experience matters.
This is where training counts.
This is professional commercial diving at its most precise.

Bay Underwater Services NZ Limited — trusted to work where others can’t.

Behind the scenes at a hydro dam 💧⚡️

Our commercial diving team is on site carrying out specialist underwater works — and also had the opportunity to take a guided tour through the dam itself. Getting insight into what happens on the other side of our dive operations helps us better understand how the entire system works, from water flow and infrastructure to power generation.

That deeper understanding supports safer, smarter, and more efficient outcomes on the job. A big thank you to the site team for sharing their knowledge and giving us the chance to see the bigger picture behind the work we do below the surface.

Big week for the Bay Underwater Services team as we head to a hydro dam to carry out essential work on the Stop Log Shutters. ⚙️💧

These projects demand precision, experience, and specialist gear — and that’s exactly what our commercial diving crew brings to the job. With an expert team, the right equipment, and years of hands-on knowledge in complex environments, we’re able to deliver safe, efficient results every time.

Another day, another dive — doing the work that keeps critical infrastructure moving.
