The community of Haast's sole police officer was assaulted and his car damaged before he was able to taser a man.
Constable Paul Gurney was called to a domestic incident about 8.20pm yesterday in an area without cellphone coverage. The nearest police back-up was about one-and-a-half hours away.
The police officer contacted someone who knew the alleged offender who agreed to come and assist.
The local volunteer fire service was also rallied.
Constable Gurney faced several physical threats and his police car sustained damage before he was able to subdue the man with the use of a Taser.
