Perrin Ag’s 3D Farm Mapping service creates a personalised video of your property using satellite imagery, letting you explore topography, contour and boundaries from multiple perspectives – without needing a farm visit.
Whether you’re a farmer reviewing your operation, a Māori trust engaging beneficial owners, or a purchaser weighing up land-use options, a 3D map gives you a richer, clearer picture of what you’re working with.
Standard aerial images are flat, top-down, and tell you little about the shape of the land. A 3D property model changes that – giving you contour, slope and spatial context that a photograph simply can’t deliver.
From satellite imagery, mapped to your boundaries, each video is:
Your base map is just the starting point. We can layer additional analysis to help you plan, manage and decide:
Financial, environmental and management assessment
Effluent systems, consents and land-use change
From riparian planting to large-scale projects
Science background with over a decade bridging land science, environmental policy and on-farm practice.
Specialist expertise in farm mapping, soil and freshwater health, and resource management.

Following University, Alastair travelled and worked extensively through Africa before taking up agricultural flying in Australia. After 10 years dodging trees, power lines and the odd cattle beast in the exhaustive heat of the Australian outback, he returned to New Zealand and took a role with the Bay of Plenty Regional Council. 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.”
Katherine brings a strong background in horticulture and environmental science to Perrin Ag, with expertise in soil and freshwater health, biodiversity, farm mapping, and resource management.
Growing up on a lifestyle block in Bombay, surrounded by kiwifruit orchards and market gardens, she developed an early appreciation for the primary industries. This led her to complete a Bachelor of Environmental Science, minoring in Planning Studies, at Massey University before gaining hands-on experience in crop agronomy, supply chain planning, and sustainability projects.
Katherine is passionate about helping farmers and growers create practical, sustainable solutions that balance productivity with environmental responsibility.
Outside of work, she enjoys trail running, mountain biking, and competing in show jumping – pursuits that reflect her love for the outdoors and a challenge.
“I’m passionate about people, the environment, and sustainable food production. At Perrin Ag, I get to work alongside farmers and growers to create positive change – for their businesses, their land, and the wider community.”
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 Farm Environment 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.”
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.”
Joel’s interest in agriculture began with his upbringing on a 1,000-hectare block of Kereru Station backing onto the Ruahine Ranges. Joel went on to earn a Bachelor of Ag Science at Massey University, laying the foundation for a career in the primary sector. On the back of a farming career and with over 12 years of professional experience, Joel joined Perrin Ag in 2024.
Joel’s ability to think outside of the box and empower others to learn and grow, means that he is well equipped to manage farm supervision and strategic planning. He has previously been involved with enhancing and supporting Māori led organisations through major development farm supervision projects.
Outside of the workplace, Joel is a family man at heart and enjoys activities like mountain biking, tramping, and hunting. Living in a modest ‘tiny house’ and running a small farm operation, Joel is passionate about growing great food and helping people understand where their food comes from – all while keeping his boots dirty.
“I help our clients step out of their daily realm and look at things through a broader lens. I am acutely aware of the mental health challenges facing our industry and the need to maintain the sustainability of our land and our people. We want farm practices that ensure long-term success without compromising farmers’ well-being.”

“I was drawn to Perrin Ag because of the passionate and dedicated team. Working with such an enthusiastic group is both inspiring and motivating.”
Mike brings a wealth of agri-tech and dairy systems expertise to Perrin Ag. After graduating with a Bachelor of AgriCommerce from Massey, he started his career with DairyNZ as a consulting officer where he ran discussion groups and managed farm supervision.
He left DairyNZ to travel the world but within a few months Covid hit, the borders closed, and Mike and his wife Nikita returned home. Back in New Zealand, he took up a role managing DairyNZ’s monitor farms on the Hauraki Plains before joining Halter.
After finishing his OE, he returned home to live in Papamoa and joined the Perrin Ag team in February 2024.
“I’m not someone who likes to sit still and I like to be continually learning. I saw an opportunity with Perrin Ag. As a business their ethos is about continuous improvement and learning. There are always new and better ways of doing things and we need to be at the forefront of that for our clients.”
Abbey joined Perrin Ag in February 2023 as part of the firm’s graduate recruitment programme, Empower.
Abbey grew up surrounded by dairy farms in a close-knit community in South Waikato. She saw first-hand how local farmers supported her community, which is what inspired her to study at Lincoln University.
Growing up in a rural community Abbey has always been impressed by how much local farmers contribute to the community. She wanted to help give back to the industry and play a part in helping our primary sector continue to produce quality food in a sustainable way.
In 2022, Abbey spent the summer as an intern on one of New Zealand’s first commercial deer milking operations. Her Honours project was researching deer milk alongside other more traditional milking operations and assessing the deer milking industry’s future production possibilities.
Abbey is currently on sabbatical leave until the end of 2025.
“Growing up I didn’t live on a farm, but I always knew I wanted to work in the farming sector. I wanted a role where there was a balance between working on and off farm and where I could support farmers to get the best out of their businesses.”
Sam grew up on a dairy farm in the Far North. After graduating from the University of Otago in 2005 with an Honours degree in molecular biotechnology, he spent several years working in medical research in New Zealand and Scotland. Upon returning to New Zealand in 2012, he spent four seasons dairy farming in Northland before purchasing a 56 ha block in Taupо̄, where he was first exposed to farming under a nitrogen cap. Sam joined Perrin Ag in 2023 and brings his strong analytical skills that are grounded by a pragmatic approach to problem solving. Outside of farming and consultancy, you’ll likely find him fly fishing, hunting or snowboarding.
“A lot of farmers feel overwhelmed in the face of a rapidly changing regulatory landscape. I strive to help farmers understand what these environmental regulations mean for their business, and offer practical solutions that allow them to keep doing what they do best, whilst remaining compliant”.
Danni grew up on a life style block in Atiamuri and spent five seasons as a relief milker in the area. During this time, her full time roles were in various fields including the rental car, health care and marine industries. Danni has had a focus on administrative and accounting duties, but is also proficient in looking after customers especially well, social media and website operation, running a rental car fleet and the associated tasks like training, rosters, H&S and organising repairs! Danni joined Perrin Ag in May 2021, to be part of a business in an industry she is passionate about.
During her spare time Danni can be found reading a book with her cats or out enjoying the walks in Rotorua’s Redwoods.
“What motivates me each day is knowing that I will be challenged with a range of problem solving tasks. I love to see all the figures adding up and knowing that my role makes a difference to the team.”
Coming from a drystock and dairy farming background, Duncan has always been passionate about growing primary sector businesses. Whether it’s pastoral farming, forestry, horticulture or investments outside the farm gate, sustainably optimising business performance 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 and project management, 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”
