Ardern said the leaders would discuss measures each nation was taking to de-escalate restrictions.
The Government announced today an easing of the rules with limits on gatherings would be lifted to 100 people on Friday.
But Ardern signalled alert level 2 could be in place until at least June 22.
Also on Wednesday, Ardern will also hold a virtual summit with Singaporean Prime Minister Lee Hsien Loong to mark the one year anniversary of the New Zealand Singapore Enhanced Partnership.
Ardern said New Zealand's relationship with Singapore had been critical in recent months to ensure critical supplies, like Covid-19 testing kits and personal protective equipment, and to ensure trade links remained open.
