The Pakistan cricket team has been denied permission to train ahead of the T20 series against the Black Caps.
It comes after several members of the squad tested positive for Covid-19.
"I have very carefully considered this situation. At this time, I continue to have ongoing concerns about the risk of cross-infection within the squad," director general of health Ashley Bloomfield said in a statement on Friday.
"There have been a number of active cases identified among the team. Public health considerations will continue to be foremost in our response to Covid-19, whether this involves individuals or teams.
"We appreciate the challenges that this decision will have for the touring team."
Seven of the squad are infected with coronavirus.
