For this week's Green Desk, Mitchell spoke to Hinewai Reserve Manager Hugh Wilson about the Hinewai Reserve, a regenerating area of native forest on the Banks Peninsula.

They discuss its carbon credit system which has become increasingly popular with large businesses allowing them to offset unavoidable greenhouse gas emissions.

The system has allowed the reserve to expand and encompass a significant area on the peninsula which has rejuvenated naturally without planting and minimal pest control. Mitchell begins by asking Wilson a little bit about the history of the Reserve and how its arrived at where it is today.
