Creditors voted on September 28 to place the company into liquidation after voluntary administrators were appointed on August 25.
"Because the international STA group has run a global treasury and finance function, this has meant that a lot of the necessary data and information have been difficult to secure," the administrators, also from Deloitte, said last month.
Deloitte continues to explore options under Government schemes to see what further support might be made available "to affected parties".
Last month the Herald reported how travel agents getting Government support could help New Zealanders caught up in the collapse of STA Travel, but they said it would be complex chasing up funds for clients of another business.
Hundreds of New Zealanders who booked through STA are out of pocket by tens of thousands of dollars.
Under an incentive scheme announced in September, agents will be paid up to $47.6m to chase up an estimated $690m held by suppliers overseas.
Flight Centre NZ managing director David Coombes was part of an industry group that negotiated with the Government and said customers of STA, now in administration, could benefit from wider sector expertise.
"My view is right now that this is firmly in the hands of creditors — nobody would be able to step in without the data and there are privacy issues, but there would be a willingness in the industry to talk to creditors and see if there is a way we could get through this," he told the Herald.
"If they think there is a pathway to utilise who is viable in the agency sector to reach out [but] it's a complicated issue."
