Police say they have been unable to locate a body at Canterbury lifestyle block where a homicide investigation is underway.
Homicide police said yesterday that a body had been found at a rural property in Woodend, 20km north of Christchurch.
But this evening, the investigation at the farmhouse took another turn.
"Subsequent enquiries have failed to locate a body at this time," police said in a statement.
"However, evidence of a very serious assault has been found at the Jelfs Rd address."
A search of the property was ongoing, and police said they had serious concerns for the wellbeing of a man named Oliver Johnston.
