Our Team

Trusted relationships

It’s hard to find people who reflect our client’s 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 would like but makes the most of it when he does.  Despite feeling like he’s swapped the paddock for the boardroom, Lee still provides dairy and dry stock farm systems advice, as well as being involved with farm business strategy, corporate governance, investment analysis and economic research.

Outside of Perrin Ag, Lee loves to spend his time refereeing rugby, watching his three kids play sport, gardening with his wife, Haidee, and indulging his seasonal passion, game bird shooting.  He tries to collect more wine and single malts than he enjoys and harbours a secret ambition to be a jazz pianist.

“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

Duncan graduated from Massey University in 2007 with a Bachelor of Applied Science in Agriculture and Agribusiness. Coming from a sheep, beef and deer farming background, Duncan’s shift into the dairy industry was the result of an opportunity on his own account to undertake a dry stock to dairy conversion. Duncan project managed the conversion then continued to run the dairy farm for a further three years following the conversion. Since joining Perrin Ag in 2011 Duncan works with a range of clients from owner-operator farm businesses through to corporate multiple land use businesses. While he has a strong background in financial analysis, business strategy 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 financial, operational and compliance challenges while helping to grow clients businesses through exploring and analysing new and innovative opportunities.”

Trudy Laan - Partner at Perrin Ag Cunsultants

Trudy Laan

Trudy graduated from Massey with an Honors degree in Agricultural Science.  Since then she has been involved in practical farming on her own account and worked as a senior tutor in agriculture. She has also been a national examiner for NZQA farm business.  Joining Perrin Ag in May 2002, Trudy works as a farm consultant in all areas of farming, specialising in dairying, corporate supervision, land use conversion and staff recruitment. 

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.”

Leighton Parker - Perrin Ag Consultants Partner

Leighton Parker

Having had years of operating as a LOSM on a 940-cow dairy in Canterbury and a consultant for New Zealand’s largest privately owned dairy corporate, Leighton made the move in 2016 with his wife Hayley and their two children to Cambridge to join the Perrin Ag team.  LOSM and consulting has given Leighton the skills and experience of large scale practical and strategic dairy farming. He is passionate about grass based, low cost systems focussing on maximising shareholder returns and also has a particular interest in profitable farming under environmental limits. 

Leighton has a growing client base of progressive and high performing dairy farmers from Canterbury though to Matamata.  Leighton has a considerable track record in helping clients achieve profitable and sustainable farm business and is currently leading new research into the sensible incorporation of forestry into pastoral farm systems.

“From a young age I have been passionate about New Zealand’s primary sector and being connected to the land.  Consultancy has allowed me to continue this passion by partnering with clients to elevate their businesses, achieve their goals, and navigate through a new farming era.”

John Perrin - Chairman of Perrin Ag Consultants Ltd

John Perrin

John has been in business as a Registered Farm Management Consultant and previously as a registered valuer for over 35 years having gained experience in Land and Survey Department immediately after leaving Lincoln University.  That experience has centred mainly around land development, farm supervision, and setting farms up for subdivision and settlement under the ballot system operating at that time. 

In the 25+ years since leaving Lands and Survey John has specialised in large-scale farm supervision, management and consultancy for Maori authorities and other absentee owners.  Since the mid 1990’s he has been predominantly involved in the design and direct management of dairy conversion projects both in New Zealand and in the USA, most latterly having had oversight for the new sheep dairy development at Waikino Station.

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

“In becoming involved in agriculture in the mid 1970’s 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.”

Peter enjoys farming his 56ha farm, playing tennis, water skiing and mountain biking with his family in his spare time.

“I just enjoy getting out to some great but often unseen areas of rural NZ to work with clients. Helping family (and corporate) teams meet challenges and achieve targets at both personal and business levels is motivating and rewarding.”

John Stantiall

In addition to one-on-one farm advisory, John specialises in group learning and farmer extension.  John currently facilitates 6 RMPP Farmer Action Groups in the lower and central North Island and works with a diverse range of sheep & beef clients from Taranaki across to Hawkes Bay.

Rachael Mitchell - Senior Consultant at Perrin Ag

Rachael Mitchell

Rachael emigrated from the UK in 1998, having been brought up rurally in Devon.  Prior to joining the Perrin Ag team in 2014 she either jointly owned or worked on three different dry stock properties, winning two Ballance Agri Nutrients Farm Environmental Awards for nutrient management and habitat creation in the process.

Rachael is one of the few independent Certified Nutrient Management Advisers in the region.  Her attention to detail and passion for her clients sees her in demand with farmers wanting to establish their current environmental footprints, implement sustainable land use change or understand compliance requirements.

In her spare time Rachael enjoys walking, swimming and photography.

“Having farmed in NZ since the late 90’s I have a real passion for the industry.  Farming under a nitrogen cap in Lake Taupō has also given me a great insight into the challenges of farming within nutrient limits.  I am passionate about helping other farmers better understand their systems in the environmental conditions they now find themselves farming in.”

Alastair MacCormick - Senior Consultant at Perrin Ag

Alastair MacCormick

Since leaving his role at the BOPRC in 2018, Alastair has relished getting back out on farm, albeit at ground level as opposed to the 3,000 feet he was used to as former ag pilot.  Alastair works extensively across the water quality space.  This 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.


“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.”

Dwayne Cowin - Senior Consultant Perrin Ag Consultants

Dwayne Cowin

What started as a childhood passion and love of being on farm, has led to a career being involved in the agricultural industry since the day Dwayne left school.

After graduating from Massey University in 2007 Dwayne embarked on a career in the sheep and beef industry. After a stint shepherding and a sole charge stock management role, Dwayne then moved onto a livestock operations manager role at Lochinver Station. After 3 years Dwayne and his wife Zara entered into an equity partnership on a 420ha sheep and beef farm located in Piopio, King Country. Dwayne and Zara still actively manage this property, and live there with their two sons Angus and Connor, and nephew Axel.

Dwayne joined Perrin Ag in 2019 and specialises in all aspects of sheep and beef farming.

Outside of farming, Dwayne’s interests include rugby (although has recently retired and is now an active arm chair critic), hunting, fishing, and water-skiing. 

“I have a passion for seeing farms develop and progress, and also enjoy being able to see the people involved demonstrate the ability to lift both productivity and profitability, without compromising their environmental footprint.  We are all only caretakers of the land, and it gives me great satisfaction seeing so many farmers leaving the farm in a better state than when they started.”

Liz Dooley - Senior Consultant at Perrin Ag

Liz Dooley

Based in our Palmerston North office, Liz spearheads much of the applied research that the firm is increasingly delivering for clients across the value chain.  Seeking research opportunities is part of her role.  Another interest is agri-tech which she is exploring with others. Liz has a PhD in agricultural systems and management.

“I am passionate about working on new ideas and new ways of doing things to positively contribute to NZ farming. As a Researcher, I enjoy exploring new systems, technologies and value chains, and interacting with the younger generation who are the future of our industry.”

This valuable time at the coalface again and the experience of operating his own business gives Daniel the ability to have a real affinity with all types of clients.
