  • Ngongotahā flood event

    On Sunday 29 April 2018, the Rotorua district was subject to a severe weather event. The rainfall depth over a six-hour period in the areas around the Ngongotahā catchment reached 145mm, with 62.5mm of rain falling in one hour.

    The Ngongotahā Stream reached its highest recorded level and overflowed its banks in several places. While flooding occurred throughout the Rotorua district, the Ngongotahā catchment experience was extreme and resulted in floodwaters inundating many homes and several businesses. Over that time 38 houses were declared insanitary and required extensive repair work. Some businesses were closed for days while they undertook repairs.

    More information about the Flood Recovery can be found here.

  • Work completed to date

    In the weeks and months following the flood, both Councils faced significant repairs to infrastructure.

    This included stopbanks, roading and stormwater network as well as the banks of the Ngongotahā Stream.
