The Isaac Conservation and Wildlife Trust

The legacy of Sir Neil and Lady Diana Isaac is a beautiful, elaborate and wide-ranging conservation space – one that upholds and protects the fragile natural treasures of New Zealand. Since our formation in 1950, conservation and the protection of endangered species has been close to our hearts, a passion that led to the creation of Peacock Springs, a unique wildlife habitat covering 1000 hectares of land on the outskirts of Christchurch for the purposes of breeding native bird species.
