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 achieved the prestigious status of becoming Registered Members along with Principal Consultant, Carla Muller. 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.

Our Board


Lee Matheson

B.Appl.Sc (Hons), FNZIPIM (Reg)

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 project managed the conversion and continued to run the dairy farm for a further three years.

With his strong background in investment analysis, business strategy and project management, Duncan is increasingly working with clients to analyse and integrate horticulture and forestry investments into their farm businesses.

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.”

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.”

Rob Brazendale


With over 30 years in the agricultural sector, Rob knows how to navigate farmers through the regulatory maze.

“Part of my job is to bridge the gap between the worlds of policy makers and farmers – to bring the on-farm perspective into the policy-making room, and vice versa. If that can be done, the environment can be respected, and farming can be sustain its profitability. New Zealand needs both.

“It’s an ever-changing world for our farmers. It’s not easy. But we can help coach them through the maze. That’s my job. It’s why I joined the Perrin Ag team.”
