The Christchurch City Mission turns 90 this month and to celebrate it has released a book called Guts and Grace.
The book covers the Mission's long history of helping the community - from its start during the Great Depression, to the changes it went through following the Canterbury quakes.
Reverend Dr Geoff Haworth is a retired Anglican priest who wrote the book and he joins us from the Christchurch studio to tell us about what he discovered.
