About Envirolink

The Company

As of 29 January 2021 the business has passed to two new owners:

David Carlson-McColl a Tasman domiciled civil engineer who previously operated Flow Environments Ltd and Martin O’Cain, also Tasman based, who has operated Tasman Environmental Management for the past 10 years. Dave and Marty have brought their previous operations under the Envirolink umbrella.

All current Envirolink staff are continuing, as are our normal services. Tony is staying on in a limited capacity to assist the transition before retiring.

Dave & Marty are keen to maintain and develop relationships with both existing and future clients. There have been a lot of changes in the freshwater industry under NES and NPSFM which are presenting challenges and changes to water users across the industry, in particular the primary sector. Both Marty and Dave bring new skill sets and experience to enhance and broaden Envirolink’s capability to meet these challenges. Also of note we are pleased to announce Fleur Tiernan has joined us as a specialist in freshwater ecology whose skills and practical experience will be invaluable in this regard.

Envirolink was established in 1988. Since then the practice has experienced steady growth in its areas of expertise.

Its growing list of clients includes forestry and mining companies, primary producers, power companies, local and regional authorities, and a host of individual clients.

Envirolink is owned by David Carlson-McColl and Martyn O’Cain.

Currently with a technical staff of five, the practice has developed links with other individuals and organisations where additional skills and experience is required.

By networking in this way, Envirolink has been able to undertake a wide range of projects in a most cost effective manner.
