Client Focused 

We care about reputation and image and to achieve that we focus on effective delivery of our service to every client on every job, no matter how big or small.

High Standards

We care about safety and compliance on our worksite that is your business.  Working to the construction diving standards requires understanding and discipline, it won’t be OK if we cannot comply with the construction diving industry standards.

Since 1978

When it comes to knowing what we are doing, we are one of the most seasoned construction diving companies in New Zealand. Founded by Ken & Annette Greenfield and now owned and operated by Brendon and Jenni Cappely.  

We Do What We Say We Will Do

When working on any project we take a realistic approach by focusing on the task that is to be performed, developing sound methodology and offering rates that are realistic to complete the job to the required standard. We don’t do cheap jobs by taking shortcuts that are invisible to the client.

Why Greenfield?


Brendon and Jenni Cappely, Greenfield, continues to provide essential engineering support and dive services to our Hydro Generation operation.

They understand the value of detailed planning, good communication, staff development and continual improvement.  They have an experienced and dedicated team who can complete the necessary tasks on time.

Most recent projects include the refurbishment of the existing intake headgate and the design build of a heat exchanger flushing system which has benefited our operation considerably whilst minimising plant downtime and lost generation.

They provide services at our power station which is situated in a very remote location, which when combined with the variable conditions can sometimes add new challenges.  Their work ethic is always professional, efficient, and compliant.

The Health and Safety focus that Greenfield brings to our worksites gives us the assurance that we have the best team in the industry maintaining our assets.

We will continue to use the Greenfield team and have no hesitation in recommending their services to others.

Generation Manager

Since my commencement of my role at the Regional Council over the last 10 years I have worked with Greenfield’s on various dive construction projects. More recently, Greenfield  have been contracted to undertake a long-term construction remediation project.

The scope of works on the project includes procurement and testing of steel, fabrication, preparation work and installation.  Greenfield have demonstrated the following attributes:

  • Compliance to strict quality assurance requirements;

  • Ability to submit reporting as per the contract requirements (monthly compliance, testing reports and payment claims);

  • Communication with the client on issues, progress and findings;

  • Understanding and working with NZS 3910:2013 contracts.

I have no hesitation on recommending them for future work.

Civil Construction Engineer

The Greenfield team were responsible not only for the safe removal of the old diffuser and installation of a new diffuser but were also contracted to assist the design consultancy in the best design for the sea conditions.  Of which the Greenfield team lead by Brendon did an excellent job in very volatile and difficult ocean and seabed conditions.


Throughout all the difficult conditions that the team were subject to, safety remained the highest priority with controls in place to ensure the team and assets were always protected from the hazards at the time.


As a client Greenfield's performance in ensuring good practical abilities, dialogue of progress and that we were always able to operate while they conducted their work has ensured we will continue to utilise their services into the future where we can.
