It is sad to see the passing of Diana, Lady Isaac, but her legacy will remain to protect the environment for generations.
Few can question her dedication to hard work - with a career that spans over 60 years as a director for Isaac Construction - she along with husband Sir Neil Isaac (who passed away in 1987) amassed an empire that will benefit the people of Canterbury and New Zealand forever.
Her award-winning Isaac Conservation and Wildlife Trust opened a 1,200-hectare conservation park on the fringe of Christchurch City, which is designed to achieve conservation outcomes and provide a recreational area.
There are not many people out there who would gift away such a huge chunk of prime land (near the airport and the city) in order to run breeding programs for endangered species and make people happy.
Like many of our successful conservationists, Lady Isaac's life was dominated by a very hard work ethic. Both before and after her husband's death in 1987, she worked as a director of Isaac Construction, but certainly not as a bookkeeper - she mucked in with the men and earned their respect - playing a key role in steering the company towards restoration of the areas that they quarried to build the Airport runway and Memorial Avenue.
