Workers at the Christchurch Casino now have until Monday next week to decide whether to take redundancy or go on leave without pay.
Last week the casino said that, due to uncertainty about when they could reopen following February's earthquake, they were not able to continue paying workers.
Christchurch Casino chief executive Brett Anderson says they had sought responses on Monday to fit in with the pay cycle, but can now give staff until 5pm next Monday to make a decision.
Len Richards from the Service and Food Workers Union says the union has been pushing for the time extension and is glad the company has listened.
About 160 workers have so far told the casino what their decision is, with three-quarters agreeing to go on leave without pay and keep their jobs.
The company hopes to gain access to the building in the next few days to allow it to assess how long it will take to reopen the casino.
