A thief robbed six women euchre players of cash and jewellery from their Hamilton motel unit as they slept metres away.
The heist happened on Sunday night when a thief gained access to the women's locked unit as they slumbered inside.
Colleen Freitas and Isla Woodham, of Hokitika, and Helen Dwyer, Chris Koh, Barbara Collett and Peggy McGee, of Greymouth, were representing the Hokitika Chartered Club at a national euchre tournament.
The group arrived back at the motel from the casino at 1.15am on their final night. Their bags were packed for the homeward journey with jewellery, cellphones and watches left close by on bedside cabinets.
The next morning, Ms Dwyer found her two eternity rings, engagement and birthstone rings, cellphone and watch had been swiped from next to where she slept. Ms Koh, sleeping in the same room, lost a new cellphone and watch.
