Monitoring Technologies Commercial Dive Limited is a specialised engineering-based commercial dive company that was launched in 2007 in response to market demand for a specialist utilities and infrastructural diving unit. Our work involves dive labour hire, pipeline inspection, pipe rehabilitation, construction and demolition as well as reservoir and intake maintenance programmes.
This coincided with the development of the Monitoring Technologies Diver DACAD system which required product testing in various environments by top of the range, highly skilled and trained commercial divers.
Divers for offshore and marine maintenance
We are fortunate to have talented, professional divers on call. Monitoring Technologies Commercial Dive is the only dive company of its type in New Zealand that provides full scoping and reporting by a qualified engineer.
Dive labour hire
Monitoring Technologies also provides dive teams on a “labour only” basis. The teams range in size from a minimum of 3 (dive Supervisor plus 2 divers) to teams of 14 (2 dive supervisors and 12 divers).
All of our dive supervisors are ADAS “Dive Supervisors” qualified and are current divers to at least ADAS Level 3. All our divers are qualified to a minimum of ADAS Level 2, with most being ADAS Level 3 and some being fully qualified saturation divers.
Monitoring Technologies will assemble dive teams to meet clients and project requirements. Depending on work load, our dive teams can often be deployed at short notice.

Removal and demolition

Commercial diving advanced risk management procedures
Given the inherently dangerous nature of commercial diving, MonTech implements rigorous project specific risk management procedures. These procedures have been developed over a number of years which represent “state of the art” methodology for managing the dive risk. The risk management procedure is based on ASNZS 4360:2004 protocols that are computerised but followed up with manual paper-based risk assessments that are performed on a daily basis on site. MonTech takes risk management very seriously and ensures all aspects of our project work conforms to industry standards as well as contemporary best practice.
