Knock Knock - confessions of a Kiwi interviewer

We've all been there. The frying pan's on the stove and the baby's crying and there's a knock on the door from someone holding a clip board. Kathryn speaks with market research interviewer Trish Palmer, who's been asking random people questions for almost 30 years. Her new book Knock Knock - Confessions of a Kiwi interviewer tells tales, some delightful some sad, from the other side of the door step. Her patch stretches from home in Kaikoura to Golden Bay.
