They appear to have lengthened the quarantine time for Category 2?
Visitors from Category 2 countries are required to spend the first (6) six nights in a designated establishment and may not leave the premises and must strictly adhere to all the conditions in place at the establishment. 3. A repeat PCR test will be performed on the 5th day. If the test result is negative, the visitors will be free to continue with their planned holiday and follow terms and conditions outlined as per the Category 1 permitted countries

So, if I understand correctly, the test is still performed on the 5th day but it's a 6 night (i.e. effectively 7 day?) minimum at the first designated establishment. We rebooked to end-Feb in the end and were planning on staying at the same place for that length of time so this doesn't really affect us but thought this might impact some peoples' plans.
