Hawke's Bay District Health Board says surgery and outpatient appointments will continue to go ahead under Covid-19 level 2 restrictions.
However, a no visitor policy has been introduced to high-risk areas.
Hawke's Bay DHB chief operating officer Chris Ash said those areas include the Emergency Department, Intensive Care Unit and the Special Care Baby Unit - this due to the size of the waiting rooms.
He said people should only visit Hawke's Bay Hospital's wards if essential.
"Discretion will be applied by the clinical nurse manager or shift co-ordinator on duty for children and anyone who needs extra care who requires a support person with them," Ash said.
