Our Team

Trusted relationships

It’s hard to find people who reflect our clients’ values.  Building trust takes time.  So does building a great team.  

All our agribusiness advisors are members of New Zealand Institute of Primary Industry Management (NZIPIM). To become a member each advisor must hold minimum academic qualifications, have been employed as a Primary Industry Professional for three continuous years and completed an ethics module. Applications also have to be supported by referees and accepted by the NZIPIM Board.

Directors Lee Matheson, Duncan Walker, Trudy Laan and John Perrin have also achieved the prestigious status of becoming Registered Members. To achieve this status they have been identified by their professional peers and clients as having a level of expertise and a high standard of delivery in the core competencies. To achieve this status they have to provide examples of work for review by peers, provide referees (including clients) and be accepted by an interview panel. As Registered Members they are also held to a high standard around professional development and are required to complete set amounts of this every year.


Lee Matheson - Perrin Ag Consultants Managing Director

Lee Matheson

Lee came to agribusiness consultancy via the unlikely pathway of a suburban Wellington upbringing, an Honours degree in plant science and a six-year career in the financial markets. In his role as the firm’s MD, Lee doesn’t get out on-farm as much as he used to but makes the most of it when he does. While having swapped the paddock for the boardroom, Lee continues to provide advice in the areas of farm business strategy, farm system innovation, corporate governance, investment analysis and economic research.

Outside of Perrin Ag, Lee loves to spend his time coaching rugby, watching his three kids play sport and gardening with his wife Haidee.

“I love the challenge of empowering people in our primary sectors and the excitement of seeing clients achieving their aspirations.  If we can encourage farmers to engage with their consumers, take a more active involvement in their supply chains and view their businesses through a wider lens, then I think our industries have a great future.”

Duncan Walker - Perrin Ag Consultants Partner

Duncan Walker

Coming from a drystock and dairy farming background, Duncan has always been passionate about growing primary sector businesses. Whether it’s dairy or drystock farming, cropping, forestry or horticulture, optimising land use, business performance and sustainability is Duncan’s passion. After graduating from Massey University with a Bachelor of Applied Science in Agribusiness, Duncan’s first opportunity to optimise a farm business was by undertaking a dairy conversion. Duncan project managed the conversion and continued to run the dairy farm for a further three years.
Since joining Perrin Ag in 2011 Duncan works with a wide range of clients including those ‘outside the farm gate’. With his strong background in investment analysis, business strategy, environmental sustainability and pastoral farm systems, Duncan is increasingly working with clients to analyse and integrate horticulture and forestry investments into their farm businesses.

“I enjoy helping clients navigate through the complexities of today’s operational, financial and environmental challenges. Seeing clients achieve their goals is very rewarding”

Trudy brings significant experience in dairy farm systems and management, along with a real passion for lifting productivity and achieving her clients’ aspirations.

“My philosophy has always been that you spend so much of your life working, that you should work at something you are passionate about and would love to do even if you were not getting paid. Having been brought up on a dairy farm where we were actively involved, I have always loved cows. I also enjoy the privilege of being trusted to assist farmers and the long term relationships we have with both staff and owners in the role as farm supervisors.”

These days John is focussed on his role as Chairman of Perrin Ag.

“In becoming involved in agriculture I was driven to help farmers and their managers maximise production and profitability from their land. Today farming is a very much more complex business and being involved in a rapidly growing advisory practice at a governance level and providing an environment where ambitious advisors and their clients achieve their joint goals and aspirations, gives me great pleasure.”

Alastair MacCormick - Senior Consultant at Perrin Ag

Alastair MacCormick

Following University, Alastair travelled and worked extensively through Africa before taking up agricultural flying in Australia.

Unwittingly entering the early stages of the water quality conundrum, Alastair spent the next 12 years working between science, policy and implementation, striving to find innovative solutions that enabled farming within environmental constraints. Alastair joined Perrin Ag in 2018 and works across the water quality space which ranges from the grass roots level with farmers wanting to continue to improve the environmental outcomes from their properties, through to how government can actually implement policy frameworks.

When he isn’t working Alastair enjoys renovating, boating and adventures with his wife and daughters.

“I enjoy working with farmers and feel for them during this time of rapid and difficult change. I believe that change is inevitable and necessary but strive to ensure it occurs in a manageable and intelligent way.”
