The real story here is Tonga v NZ being moved to potentially post season.https://www.thesun.co.uk/sport/1032...merge-as-possible-2020-opponents-for-england/
New Zealand and Samoa seem to be the preferred opponents for England, but Cook Islands and Fiji are in the mix.
But then, who would Tonga play mid year? Would have to be Fiji? To get the Oceanic Cup games underway?
If they played against Samoa for instance, there could be no Pool A fixture, and they would need to play all games at end of season.
