Reliable Moorings Across New Zealand
Marine Services NZ (MSNZ) is a New Zealand-wide mooring provider, currently maintaining more than 1,500 moorings in the Marlborough region alone, with a growing portfolio in Stewart Island and Fiordland.
We deliver complete mooring solutions nationwide – including installation, system upgrades, compliance inspections and biennial servicing. From traditional chain moorings to environmentally friendly screw-anchor systems, vessel owners across Marlborough, Stewart Island, Fiordland and beyond trust MSNZ for safe, precision-placed moorings.
SALM & MALM Mooring Systems
MSNZ’s Single Anchor Leg Mooring (SALM) system uses screw anchor technology and high-buoyancy floats to create a secure, low-impact mooring that’s gentle on the environment and your vessel.
For larger vessels and deeper waters, our Multi Anchor Leg Mooring (MALM) system distributes the load across multiple anchor points to increase stability and strength. Also as the pivot point is much closer to the surface the swing circles are much smaller. Eg. 40 metre vessel in 70 metres of water the swing circle is only 65-70 metres with a 20 metre set of Top Ropes.

Marine Flex Installations
MSNZ is a licensed installer and servicer of Marine Flex – a high-performance elasticated mooring system that reduces shock loading, protects seabeds, and extends the life of your gear. Marine Flex is ideal for eco-sensitive locations and long-term reliability.
Concrete Block Supply & Installation
We supply and install engineered concrete blocks from 2 to 5 tonnes, depending on your system requirements. Our vessels, Soundz Image and Soul Commitment, are purpose-built for anchoring and mooring work and can lift or deploy blocks up to 6 tonnes from the seabed with ease.
Using our Differential Global Positioning System (DGPS), we can accurately place, locate or reposition your mooring block as needed.
Commercial Diver Support
Our team of qualified commercial divers ensures all mooring work is carried out with precision and care. When lifting mooring blocks, we always attach at the block eye rather than by the tackle to avoid unnecessary strain on mooring components.
If your mooring buoy sinks or goes missing, we can still locate and recover the tackle and block underwater.
Mooring Inspections & Maintenance
To maintain the safety and reliability of your system—and to comply with regional requirements—we offer a biennial servicing and maintenance programme.
We’ll contact you before your service is due, complete a full inspection, and provide a detailed servicing report. This includes:
-
Checking all mooring tackle
-
Replacing worn components (as recommended by Marlborough District Council’s Minimum Mooring Standards, components should be changed at 20% wear)
-
Welding for added security
-
Fitting anodes to extend the lifespan of components
We carry spare stock onboard and stand by our workmanship under the Consumer Guarantees Act 1993. A Mooring Certificate of Compliance will be issued after each service.
Mooring Cleaning
Between inspections, marine growth can quickly build up on mooring lines, especially in warmer months. MSNZ offers a mooring cleaning service to help reduce the risk of fouling and buoy sinking.
You can choose a one-off clean or schedule a regular annual clean in alternate years between inspections.

Frequently Asked Questions About Moorings
How often does my mooring need to be serviced?
Mooring inspection requirements for Marlborough District Council are at intervals not exceeding two years. However, your individual mooring consent may state otherwise – please refer to your consent conditions for exact timing.
Why is my mooring sinking?
Heavy fouling can cause your mooring to lose buoyancy and sink. To prevent this, clean the top rope every 8–12 months. If you’re already experiencing sinking, get in touch so we can assess and remedy your fouling issues.
My Mooring Resource Consent is due to expire. Can you assist with my Renewal?
Yes. We can complete your application for you. Please enquire for costs.
