Fig. 2. The breached Waiouru maar crater and tuff ring (seen here in 1993) recently opened
as a public reserve as part of the new Highbrook Industrial Estate subdivision, Otara. The
subdivision included the construction of an arterial road just outside of the tuff ring which
separates it from the Tamaki Estuary. Sometimes called Pukekiwiriki,, local iwi restrict this
name to Red Hill volcano, Papakura.
Fig. 3. Mangere Lagoon maar crater served as sludge ponds for Auckland sewage from 1959
to 2003. Subsequently restored to an intertidal inlet, with the central scoria cone rebuilt, the
whole has been opened to the public as an extension to Ambury Regional Park.
