Kia whakahaumaru te whānau, me ngā iwi katoa – this is to keep everybody safe:
By sticking to the rules above, you help keep our patients, staff, other visitors and yourself safe. We thank you in advance for your patience and understanding as our staff work hard to protect and care for some of the most vulnerable in our community.
Exceptions to the ‘one visitor’ policy
Visiting patients with COVID-19
You must NOT visit the hospital if you
Exceptions for people with disabilities
An exception will be made for people with disabilities who are in hospital or have to attend an outpatient appointment – where they need a support person to access health services. For example, a sign language interpreter, support person for someone with a learning disability, or someone to assist with mobility. The support person is in addition to the one permitted visitor.
Everyone visiting our facilities must wear a mask, no exceptions
While we appreciate that some people have legitimate reasons for being exempt from wearing a mask and may even have an official card to confirm this, people who cannot or will not wear a mask cannot visit someone in hospital or attend hospital, other than to access healthcare. This is another measure to minimise the risk to vulnerable patients.
Patients and visitors should also read the additional more detailed visiting guidelines for each specific hospital.

A 15 ug/L cutoff is employed to rule out the likelihood of a positive result occurring from side-stream exposure.
All results less than 15 ug/L are reported as not detected. Results greater than 15 ug/L are resulted with a number and also a carboxy-THC to creatinine ratio. |
