Almost all of the "higher risk" workers have been tested, the Port of Tauranga has confirmed.
A port spokeswoman believed most of the workers in the priority group had been tested by the end of Wednesday, aside from those with different shifts or on leave.
About 320 port workers were tested at the Port of Tauranga's dedicated testing facility on Tuesday, the Bay of Plenty District Health Board confirmed, following about 160 workers between midday and 4pm on Monday.
On Friday, the Ministry of Health ordered up to 6000 Port of Tauranga workers to be tested by midnight on Monday. The public health order was then amended on Monday night - extending the testing deadline to 11.59pm on August 20 and clarifying "high-risk" workers.
