Cornerstone Roses is a small, family-run rose grower on its own farm in Riwaka, in the Tasman region, formerly known as Tasman Bay Roses. The roses are grown on the farm, and the business says it grows them sustainably.

Potted roses are for sale, and orders can be placed in person at 144 Lodder Lane, Riwaka, or online. Anyone wanting advice on rose care can use the enquiry form on the website or call the nursery.
Riwaka is a village in the Tasman Bay area, and the farm's roses are aimed at gardeners across the region and at people sending gifts. The business describes itself as a family business with a passion for bringing the beauty of nature into homes and gardens. The website shows photos of the nursery from the 2025/26 summer.
