More than 240 Napier port workers have been tested for Covid-19 as part of surveillance testing ordered by the director general of health.
On Friday with no warning, Dr Ashley Bloomfield ordered "everyone who works at the maritime border" to be tested by 11.59pm on Monday night. Testing applied for all people who worked at ports around New Zealand who might come into contact with ships' crew.
A Hawke's Bay District Health Board spokeswoman said it had tested 242 workers by Monday afternoon.
The workers were among more than 530 people tested in Hawke's Bay over the weekend, with no one returning a positive test so far, though the results of some tests are yet to come back.
Hawke's Bay District Health Board medical officer of health Dr Nick Jones said because of the numbers of people coming forward to be tested there were some delays in getting a test that same day, but testing staff were working quickly through the backlog.
