Christchurch Police have charged a teenager with murder, following the death of a man at a rural Canterbury property last week.

Police have identified the body as that of 20-year-old Oliver Johnston, also known as Oliver Greene.

Christchurch Police were told on Thursday a man's body had been found at a house on Jelfs Road in the small community of Woodend, north of the city.

Police initially couldn't find the body, but did find evidence at the address that a very serious assault had taken place.

The following day they located the body of Mr Johnston, and yesterday, arrested and charged an 18-year-old man with murder.

He'll appear in the Christchurch District Court this morning.
