TreeGen - Planting for the Future


We are your New Zealand native revegetation specialists. Our company was founded in 2016 by local girl Shelly Walker. Shelly grew up on the East Coast, and always had a love for plants. After 25 years in the horticulture industry, Shelly finally decided to follow her passion for environmental restoration. She shifted focus to concentrate on improving degraded land and creating flourishing natural habitats through revegetation; TreeGen was born. Our team all share Shelly's passion and vision and bring their own unique skills and experience to their work. While Terry's in the office writing reports, Mark and Murray might be out planting or keeping our gear in top shape, meanwhile Stacey is creating amazing planting plans. And Shelly? She's probably visiting the site with you, bouncing ideas back and forth, and helping you pull off a stunning revegetation project in your special place.
