There's no guarantee businesses will honour unredeemed vouchers from GrabOne, which has gone into liquidation.

The online deals website won’t be issuing refunds for unused purchases - and has told customers to directly contact vendors.

Some sellers have indicated they’ll recognise GrabOne deals, but others say they may not be able to.

Parakai Springs general manager Dion Tilson says they will honour vouchers, but customers could lose-out at other companies.

"I've spoken to a lot of businesses, restaurants and so forth, hotels - they may not be in a position to be able to offer it."
