Passengers arriving from more parts of the UK face longer periods of isolation on arrival in Guernsey, ahead of the border restrictions easing on Thursday (1 July).
Among the latest changes to the Bailiwick's travel list, the East Midlands, South East, and South West of England have moved to Category 4.
That means everyone arriving here from those areas before Thursday must isolate until a negative Day 13 test.
After 1 July, only those who have not had two doses of a coronavirus vaccine at least a fortnight before travelling will be subject to that isolation period.
South West Wales has become Category 3 - requiring seven days quarantine.
Jersey has been put on the Category 3 watchlist, along with the East of England - meaning both are likely to move to Category 4 in a week's time.
Other changes that took effect at midnight include:
Cyprus from Category 3 to Category 3 watchlist.
Madeira, Scotland Islands (Orkney, Shetlands, Western Isles) from Category 2 to Category 2 watchlist.
Monaco from Category 3 watchlist to Category 4.
Corsica and Serbia from Category 3 to Category 2.
Denmark, Greece, Netherlands and Slovenia from Category 4 to Category 3.
Meanwhile, anyone arriving into England solely to travel directly onto the Bailiwick no longer has to purchase a UK travel test package
They will still need to have a negative result from a pre-departure Covid-19 test and have completed the passenger locator form.
Arrivals from a country on the UK’s red list will still be required to complete the mandatory hotel quarantine in England before continuing on to the Bailiwick.
