189:. The Hikurangi subduction zone is one of New Zealand's most significant geological hazards and can result in earthquakes and tsunamis. The Hikurangi Ocean Bottom Investigation of Tremor and Slow Slip (HOBITSS) project included a network of seafloor instruments that could measure the vertical movement of the seafloor, deployed from the R/V Tangaroa. This instrumentation allowed for high resolution mapping of an area that was previously inaccessible. The slow slip events that occurred in the Hikurangi occurred for about two weeks and can cause up to 20 cm of movement along the New Zealand and
