Large-scale relict landslides affect around 80% of the East Coast Bays Formation (ECBF) on the O Mahurangi (Penlink) project.

These landslides provide an insight into the widespread instability within the Waitemata Hill Country, also referred to as the Northern Landslide Zone. Presenters from the O Mahurangi project will share geological insights, engineering challenges, and practical lessons from constructing through some of the most difficult ground conditions in northern Auckland.
