Our team

Ross is a born and bred orchardist with more than 40 years' experience in sourcing, developing and, managing land, establishing and managing orchards and project-managing and operating packhouses. He has a deep understanding of horticulture and how to maximise production.

His broad experience includes all the practical aspects of husbandry, such as the latest machinery developments, irrigation set up, sprays, crop protection and compliances.

This knowledge, combined with the invaluable experience he has in effectively managing and setting up orchards and packhouses, plus his constant push to bring new technology, systems, and techniques – sourced from the best in the world – into the business, means he is at the leading edge of horticulture production in New Zealand.

Ross is renowned for designing his own equipment in a quest to create efficiencies and be ahead of the curve in New Zealand cherry production. While overseeing two significant planting phases at Lindis Peaks and Mt Pisa orchards for Deep Creek Fruits NZ LP, Ross designed a planting machine, which was built to his specifications. The machine enables up to 6,000 trees a day to be planted, nearly double that achieved previously.

In 2022, he project-managed the construction and fit-out of the state-of-the-art Lindis Coolpac packhouse. The packhouse was the third packhouse Ross had project managed from greenfield to turnkey site in the Central Otago region since 2014.

Ross oversees multiple crews to develop and manage orchards at Mt Pisa, Lindis Peaks and Ardgour Valley Orchards, Central Otago. He is formerly project and orchard development manager of Tarras Cherry Corp.

He attended Massey University to study for a Diploma of Horticulture.

A love of the outdoors and farming inspired Loren Lilley to embark on a career in horticulture.

Loren joined the Hortinvest team in late 2023 just in time for cherry season, after completing a Bachelor of Agricommerce at Lincoln University.

Her farming journey began growing up on a kiwifruit orchard in the Bay of Plenty region and she was equally inspired by her father, a dairy farmer.

Loren, who relocated to Wanaka to assume her position, is assigned to the Lindis Peaks cherry orchard where she is an orchard worker responsible for general crop work and orchard maintenance.

She embraces all aspects of orchard life, especially working outside, discovering the beauty of the Central Otago region and the opportunity to learn about what goes into producing cherries for the export market.

Growing up, much of Makayla Rasmussen’s time was spent outside mountain biking, horse riding and tramping – making for an easy transition to her role where she works in all kinds of weather.

Makayla started as a casual in winter 2021 and seized the opportunity to take on an apprenticeship when it arose, relishing the chance to discover the world of horticulture and learn an array of new skills.

Makayla’s duties include spraying, pruning, ground preparation and maintenance, fruit harvest management and post-harvest care at Ardgour Valley Orchards.

Before joining the team, Makayla was employed as a horse groom at Taupo Hunt Master, Reporoa on the North Island, where she managed six horses.

He has embraced the opportunity to further his career in horticulture and learn a range of skills in orchard production including tractor and machinery operation.

He joined during the team during the 2021 planting season, bringing four years’ experience in cherry production including pruning, planting and harvest. He is also familiar with the end-stage of the cherry supply chain, having worked five seasons in a cherry packhouse until 2018. His experience extends to a winery where he was employed as a bottling hand.

David Mackessy applies a knowledge of farm machinery and equipment gained over more than 20 years to his role at Hortinvest.

He grew up on a dairy farm in Ireland which gave him a sound knowledge of farming practices and machinery. David later moved to London where he spent 20 years working as a plant fitter, fabricator welder and machine operator.

While on holidays in New Zealand in 2003, he decided to stay and now calls “the land of the long white cloud”, home. He has experience working on agricultural, construction, vehicle and site equipment in the United Kingdom and New Zealand.

David is trade certified as a mechanical engineer and has a National Diploma in Engineering from Rycotewood College, Thame, Oxfordshire. He joined the Hortinvest team in 2021.

Orchard worker Anahera Roberts was so inspired by her brother Maaka’s experience at Hortinvest that she decided to join him and begin her journey into the world of growing fruit.

In her first year out of high school, Anahera had left her hometown of Invercargill to move to Wanaka to live and work alongside Maaka and the team at Lindis Peaks orchard where premium cherries are grown for the global export market.

It has been a steep learning curve for Anahera, who enjoys learning how to operate machinery and carry out orchard work such as spraying, pruning and thinning, in all kinds of weather.

She enjoys living and working in an environment different from the one she grew up in, as well as learning about the cultures and ethnicities of her colleagues.

Arriving in mid-winter 2023, Anahera was struck by how much goes on behind the scenes in the orchard such as frost-fighting and the attention to detail paid to every tree to ensure they are in the best of health.

Fresh out of school and ready to work, Noah Bayliss joined the Mt Pisa orchard team in September 2024.

Previously from Queenstown, he moved to Wanaka to be closer to work and is reaping the rewards of that decision. He enjoys working outside in the fresh mountain air and learning about cherry production, specifically his main task as crop sprayer.

One of his favourite things about living and working in Central Otago is seeing snow on the mountains. Noah is also a keen snowboarder and skate boarder.
