Ross Kirk

Co-founder, project & orchard development manager

Ross is a born and bred orchardist with more than 40 years' experience in sourcing, developing and, managing land, 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, 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 Tarras Cherry Corp, Mt Pisa, Lindis Peaks and Ardgour Valley Orchards, Central Otago.

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

Loren Lilley

Orchard worker

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.

Anahera Roberts

Orchard worker

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.
