From Acorn TV:

Detective Inspector Mike Shepherd arrives on assignment in Brokenwood, a small town where memories-and animosities–run deep. He’s an experienced cop with a 1971 classic car, a collection of country music cassettes, and an indeterminate number of ex-wives. The new woman in his life is his assistant, Detective Constable Kristin Sims (Fern Sutherland, The Almighty Johnsons), a by-the-book investigator 15 years younger than her boss’s car.

From Acorn TV you can stream two seasons: Season 1 has 4 episodes. Season 2 has 4 episodes.

In keeping with its mandate, Acorn brings us this detective series from Australia. Each episode is self-contained and lasts about an hour and a half. This series is one of so many detective TV series available that there is nothing that distinguishes “Brokenwood Mysteries”. But the plots are interesting, the characters are well done, and the butler did not always commit the crime.

Acceptable Australian detective series.
