New Zealand Cricket chief executive David White has cast doubts over the tour of West Indies in July in the wake of the coronavirus pandemic.
Additionally, New Zealand's spate of limited-overs fixtures in Ireland, Scotland and the Netherlands in the summer are likely to be postponed.
New Zealand's two-Test assignment against Bangladesh in August-September this year could be subjected to a delay as well.
"Clearly, this situation is extremely disappointing for everyone involved in sport but, given the bigger picture, and the terrible toll COVID-19 is taking worldwide, we need to look after not only our own people but the greater community good," White said.
Meanwhile, NZC confirmed the women's tour of Sri Lanka had been cancelled.
The potential postponement of New Zealand's series in the Caribbean could create serious financial ramifications for the host board.
The rising number of COVID-19 cases in New Zealand has compelled the government to impose a nationwide lockdown with White reiterating the fact that the priority lay in ensuring the domestic season would go ahead as planned.
"Our current focus is very much on ensuring the future sustainability of cricket in New Zealand," White claimed.
