If you're after another podcast about the search for family members, the new RNZ podcast The Sound Of My Father is for you. When documentary maker Rita Attwood discovers a cassette tape with a 60-year-old, unheard recording on it, she sets out to help John Court, her step-dad, on a journey of self-discovery. Born to a US Marine and a wahine Maori who fell in love in World War II, John's search also reveals a hidden New Zealand history.
