Possibility minor eruption White Island.

Update. 7 June 12.00am.
Local and Pacific quakes were quiet on 6 June...except Kilauea.
The big Kawerau quake swarm has settled down on 6 June and a good indicator of a volcanic pickup.
Today Geonet have announced heating since 31 May at Ruapehu.
The 24-27 May Aotearoa Summary speculated volcanic heating in New Zealand was near so today's announcement is good confirmation.
The Ruapehu heating gives credit to the addition of White Island as a steam eruption risk...although no eruption has taken place yet.
The forecast period is heavily volcanic in the Pacific.
Bay of Plenty remains highest risk location on 7 June.
The forecast period is likely to close soon.
