Christchurch Hospital has reopened a surgical ward where the so-called superbug MRSA was detected in five patients earlier this week.
MRSA is a type of Staphylococcus aureaus bacteria that has become resistant to many antibiotics commonly used to treat infections.
The Canterbury DHB says none of the patients were unwell because of the bug and there were no new cases of patient infection.
The hospital's interim general manager, Ruth Barclay, says the infection control team and surgical ward staff have worked hard to enable the ward to be reopened.
Staff will continue to monitor the situation closely and remind patients and hospital visitors to wash their hands, she says.
