The Spring Hill prison guard who tested positive for Covid-19 on Sunday is no longer being considered a positive case after further investigation.
In a statement from Corrections NZ chief custodial officer Neal Beales, he gave no explanation as to why the Waikato prison guard was no longer being treated as a positive case.
The guard, who had no symptoms and was fully vaccinated, had visited a location of interest in Auckland.
After the test result was known, 23 staff who had been in contact with the guard self-isolated and were tested, and the unit the guard worked in was deep-cleaned.
