PORT Adelaide chairman David Koch has whacked assistant coach Michael Voss, calling on him to not meet with other clubs until season's end.

FULL FIXTURE Every round, every game

Voss met with Carlton earlier this week regarding the Blues' senior coaching vacancy, and on Friday morning, Koch expressed his annoyance with the situation on Sunrise.

"People go for better jobs. That's great, but do it at the end of the season," Koch said.

"Focus on the job at hand. We're paying you at the moment. Do your job. Show your interest (in other jobs), but hey, get focused."

His comments are in contradiction with what Voss said on Thursday.

"The fact that I've had the club's support is obviously pretty important. It doesn't shift off what your focus is here," Voss said.

Port coach Ken Hinkley weighed into the controversy on Friday at his press conference, after Koch had made his comments.

"These things go on consistently throughout the industry. We all get that, we all understand that. Is there a better way to do it? I'm not sure just yet we have got that better way," Hinkley said.

Hinkley had no doubts about Voss' dedication to his current role.

"Every person that works for us is totally focused on their job at Port Adelaide," Hinkley said.

The Power sit in ninth spot at 8-8 after being soundly beaten by Brisbane last Sunday.

Voss told the In the Game with Damian Barrett podcast in May he wanted to be a head coach again.

He previously was in charge of the Lions in 2009-13 and has been with the Power since 2015.

St Kilda also has an opening after Alan Richardson resigned on Tuesday, while North Melbourne is seeking to replace Brad Scott, although Rhyce Shaw is expected to be elevated from the caretaker role to a full-time position.

Port face Richmond on Saturday afternoon at the MCG.
