Mid-1980s series Then Again revisited high profile moments in Kiwi history, mixing archive material and interviews with those who were there. This item from a 1986 episode looks back at the Strongman mine explosion of 19 January 1967, which killed 19 men at New Zealand's largest underground coal mine. Twenty years on reporter Jim Hopkins visits the still-working West Coast mine, to see if ghosts still linger. An official inquiry found that the state-run coal mine had neglected safety procedures; the Government paid compensation to families of the victims.
