This came barely days after the social media was awash with speculations that he was admitted to a South African hospital with an undisclosed disease.
The Facebook posts claimed senior officers were repramanding law enforcers who were leaking the story.
However, police spokesman at Area 30, James Kadadzera refuted the allegations.
At the Area 30 senior officers end of year party, Kachama was represented by Willie Mwaluka, senior assistant deputy commissioner of police.
He did not say anything on the IG but applauded police officers for the job well done in 2016.
Mwaluka said 66 police officers died in 2016, half of whom died in line of duty.
