11 new caps featured in Samoa's two wins over Tonga in July, which secured their spot in the 2023 Rugby World Cup.
Two third of that squad were based in New Zealand and Australia, because of the travel restrictions imposed by Covid-19.
Lakapi Samoa's General Manager of High Performance, Seumanu Douglas Ngau Chun, said the latest outbreaks in both countries mean they will focus their selections on players already playing in the north.
"Definitely it's a big no for us from New Zealand," he said.
