HP South Pacific managing director, David Caspari, has departed.
The vendor could not comment on if he would be replaced at this stage or supply further details on his departure.
In the meantime, HP's vice-president of technology services support Asia Pacific and Japan, Howard Bowland, will take on Caspari's responsibilities, on top of his current role.
Caspari took on the top job in May last year, replacing Paul Brandling at the time.
Caspari joined HP in 2007 as senior vice-president for sales across Asia-Pacific and Japan. He has also previously worked for Cisco for four years and Nortel.
