Intense downpours in Tairāwhiti overnight cleared on Thursday morning.
Two-hundred millimetres of rain was recorded in the northern part of the region in the five hours to midnight, on top of heavy downpours earlier in the day.
Damage from yesterday's storm left people from Wairoa to the top of East Cape without power through the night.
Crews will be back out this morning trying to get them reconnected.
Roads that were closed overnight due to slips and fallen trees will also be reviewed this morning.
RNZ reporter Jimmy Ellingham spoke to Susie Ferguson from Wairoa.
