There will still be a market on Saturday and while only food and fresh produce vendors will be allowed to take part, strict conditions will apply to them.
For example, each vendor will need to maintain separation of at least two metres between stalls.
Cook Islands Secretary of Health Dr Aumea Herman said Te Marae Ora Cook Islands Ministry of Health recognise that providing fresh foods are an essential service at the market.
Although there are not yet any confirmed cases of Covid-19 in Rarotonga, more than 80 people have been tested.
While 11 test results were negative, health authorities believe we should be behaving as if the virus is here and take all the precautions outlined by Te Marae Ora.
That includes regular hand washing, maintaining physical distances of two metres from each other, no kissing, handshakes and most of all stay home unless it is absolutely essential to go out.
