Napier mayor Kirsten Wise last night declared a state of emergency with weather experts calling yesterday's event "record-breaking" and now officially the second wettest day in the city since records began.

As of about 10pm yesterday, 237mm of rain had been recorded since 9am. Niwa said the wettest hour on record, since 1995, is 54mm.
