Moderate solar conditions have driven equatorial Pacific action but New Zealand is quiet so far during the period.
The week long White Island quake swarm has ended for now.
Solar conditions are fading on 1 June but may have enough energy to drive a late isolated quake.
Risk locations and Magnitudes are unchanged.
Volcanic Plateau and Bay of Plenty are hotspots.

The forecast period began on cue with only moderate spaceweather.
Quakes quickly arrived north of New Zealand.
Spaceweather faded on 1 June, quakes faded and the forecast was dropped.
Moderate spaceweather arrived unexpectedly early 4 June and the East Cape 5.4 soon followed.
Quakes continued in risk location hotspots as earlier.
The week long White Island Mag 3 quake swarm ended early in the period but a new swarm started at Atiamuri.
The very large April Gisborne slow slip event was a good indicator that big tectonic action is just around the corner in New Zealand.
Previous slow slip events have been precursors for large quakes.
September, October, November seem more likely for a bigger local quake as the solar connection increases with the spring aurora season.
A new forecast period begins 10 June.
