Bethlehem's Bob Owens Retirement Village has been battling a highly contagious vomiting and diarrhoea illness for nearly a week, with one resident admitted to hospital.
Forty-six residents and two staff have succumbed to the suspected norovirus stomach bug since the first case was notified to Toi Te Ora Health last Thursday.
Ryman Healthcare spokesman David King said it was the third outbreak in the village over the last 12 months.
"It has presented as a short, sharp 24-hour bug."
With six people still affected by the illness, he believed the village was through the worst of it. "One person went to hospital as a precaution and has recovered."
