Mount Maunganui landslide: Why rockfall was largely left out of new slip risk study

Tauranga City Council is reviewing landslide risks at Mauao following a fatal incident, though recent reports have been criticized for omitting rockfall hazards. Local officials are now debating risk tolerance thresholds for public facilities at the base of the mountain.

Councillors have received a new assessment of landslide risks on Mauao, but no decisions have been made about the future of council facilities at its base.
In a Wednesday meeting, Tauranga City councillors heard more information was needed about rockfall risks, which were largely left out of the landslide report.
Councillors discussed the new Quantitative Landslide Risk Assessment (QLRA) report for the mountain in the meeting, which continued Tuesday’s landslide response discussion .
This came after former High Court judge Paul Davison’s review of January’s tragedy found council missed opportunities for years to take action that could have prevented the deaths of six holidaymakers at the Mount Maunganui Beachside Holiday Park.
