Blackmores chief executive Henfrey resigns

Health supplement company Blackmores says its chief executive officer has resigned after 18 months on the job.

Richard Henfrey, who has been with the company in a variety of executive roles since April 2009, will remain in the position while the board searches for a new CEO.

The company did not state a reason for his resignation.

Blackmores shares hit an 18-month low last week after the vitamin maker told investors not to expect an increase in sales to China.

Blackmore shares were down 4.1 per cent, or $3.90, to $91.30 at 1012 AEDT.
