The healthcare group had learnt a lot from its villages in Australia so was being cautious and putting its residents first, he said.
It was hoped that the restrictions wouldn't be in place too long.
Ryman residents living independently in the villages were unaffected and could still come and go as they pleased.
Staff were also having Rapid Antigen Tests every day as another safety measure.
Meanwhile, Summerset has also only been allowing visitors to its Auckland village care centres on compassionate grounds since Sunday.
It is one of a number of preventative measures Summerset is taking to try and spread in its villages, according to an email sent to residents and their families.
Independent residents living in Summerset's main buildings have also been asked to restrict the number of visitors to one.
The restrictions would be lifted once Auckland had reached its peak number of cases, the email said.
