A theme park on Queensland's Gold Coast says it is confident safety issues that stopped a rollercoaster yesterday have been fixed.

The Green Lantern at Movieworld was stopped in its tracks twice yesterday.

Just before midday, eight teenagers were forced to spend 70 minutes on the stalled ride 13 metres above the ground.

Movieworld spokesman Darrin Davies says a minor wiring problem was to blame.

"The sensor light that came on was enough to cause the ride to stop," he said.

"We made sure that everybody had water and shelter and we sent staff up there to be with them while we rectified the problem."

A safety system shut power to the same ride some time later.

Eight other passengers spent around half an hour on the rollercoaster while the problem was identified and fixed.

Mr Davies says the ride resumed after testing.

"We have very skilled and talented maintenance and technical people here and the issue for them is safety," he said.

Mr Davies says yesterday's stoppages will be fully investigated and it will be business as usual at the theme park today.
