Waikato Hospital has locked down a ward after multiple transmissions of Covid-19 between patients.
"Waikato Hospital is pausing new admissions to ward M14 as we have identified transmission of Covid-19 within the ward," a spokesperson from Te Whatu Ora Waikato confirmed.
A source told the Herald this ward looks after patients following cardiac surgery, and also vascular patients.
In a memorandum, provided to the Herald, Waikato Hospital staff were told the situation was "ongoing and difficult to control".
"This leaves us down 30 beds on top of an already dire situation," the memo read.
"We are potentially entering the most difficult time of year so far in the next couple of weeks."
