In the early 90s, Jim Lynch dreamed about creating the world's first predator fenced community eco-sanctuary.
And today the sanctuary, now known as Zealandia, is still going strong. In fact it's a success - it's achieved its restoration goals and is a major attraction in our capital city.
That journey to success is detailed in a new book Zealandia: The valley that changed a nation and Jim Lynch is here to tell us more about how he made his dream come true.
