UPDATED 2.40PM An emotional head of the company that runs Dreamworld refused to discuss her pending performance bonus at a press conference.

Theme park operator Ardent Leisure's AGM is being held today - just two days after four people died on a ride at Dreamworld.

CEO Deborah Thomas would not be drawn on the fact she could soon be receiving a bonus of almost $920,000 NZD.

"I don't think it's appropriate under the circumstances. Four people died, very recently, and we are all shattered by it."

"This is not something that you deal with very easily so right now I don't want to discuss transactions."

Ardent Leisure's chairman Nigel Balnaves has responded to criticism for going ahead with the company's AGM just days after the accident.

He said under the corporation's law they were unable to defer the meeting.

"None of us had a great desire to stand here today in the middle of this crisis and have an AGM - we're compelled under law to do it."

Dreamworld will reopen for normal business from Saturday but the Thunder River Rapids Ride, where four people died on Tuesday, could remain closed for years.

Balnaves said after a lot of deliberation they've followed advice from psychologists and counsellors - that it's better that people get back to work.

"And basically get together with their comrades and talk and deal with this issue, rather than being concerned about their jobs, and they're sitting at home in isolation, and we're just adding to their issues."
