Duggan was a TVNZ police drama from 1997, featuring New Zealand actor John Bach as Detective Inspector John Duggan and Fiona Mogridge as Ruth Duggan. Unlike other New Zealand police drama series, Duggan was initially intended to be produced as a series of one-off programmes, akin to British crime series of the time such as Inspector Morse and Midsomer Murders. Two stories were filmed in this way, one each in 1997 and 1998, before the decision was made to produce a series of 11 episodes in 1999. All episodes except for the first two were one hour in length; the first two were two hours long.
