Wairoa was not far behind recording 32.9 degrees in the last hour, which breaks a four year old record.
Hastings joined the record breaking club reaching 32 degrees, which topped their previous high of 31.7 last year.
Ms Flynn said all of the necessary ingredients had lined up producing these sweltering temperatures and the foehn effect.
"Foehn winds are produced as Napier sits to the east of the ranges, so as the air comes over it dries out and heats up a lot."
Tomorrow this changes as the winds will come directly off the sea producing sea breezes and cooler air.
"We will see a drop in temperatures, as they will be sitting around the early to mid twenties."
Napier is expected to drop to 21 degrees while Hastings drops to 23 degrees.
