Sustainable Tennis balls are usually made to last longer than regular balls. But, because whacking a ball as hard as you can in a game of backyard cricket increases your chances of losing it, we wanted to create a ball that lasts less time than a regular one – not more.

The ASB Sustainaball is a biodegradable tennis ball, manufactured from 95% natural rubber, and wrapped in 100% natural wool felt. The Sustainaball contains a selection of native New Zealand seeds, including Kowhai, Mahoe, Pigonwood and Pohutakawa, which are applied to the ball with a water-soluble sticker. So, if you lose (which we don’t want you to do), you’ll be planting a tree – and a home for native birds such as tui, hihi and korimako.
