A new book written about the life of a remarkable Southland doctor has proven to be so popular it's already sold out of its initial print run.
Southland historian and author Lloyd Esler self-published the book called 'Dr Eric Elder of Tuatapere'. It outlines the life of Dr Elder, a doctor in the small Southland town from for 49 years, from 1938 to 1987.
It's Esler's 12th book, and he joins Mark Leishman from Invercargill to share his secret to the book's success.
