The region is located in the northeastern corner of the
North Island. It ranges from the Wharerata Hills in the south, which divide it from
Wairoa District in
Hawke's Bay, to
Lottin Point in the north. The western boundary runs along the
Raukumara Range, which separates it from
Ōpōtiki District. In the southwest, its boundary runs along the western edge of
Te Urewera. It is sparsely inhabited and isolated, with small settlements mainly clinging to small bays along the eastern shore, including
Tokomaru Bay and
Tolaga Bay. Its population is Three-quarters of the population – – lives in the city of Gisborne. No other settlements have a population of over 1000; the largest are the towns of Tolaga Bay and
Ruatoria, each with populations of over 800 in 2001. Inland, the land is rough, predominantly forested, hill country. A spine of rough ridges dominates the centre of the region, culminating in the impressive bulk of the 1752 metre
Mount Hikurangi in
Waiapu Valley in the region's northeast. Hikurangi is the fifth-highest mountain in the North Island, and the highest that is not a volcano. Regarded as sacred by
Māori, there is some justification to the claims that this is the first mountain to see the sun in summer. The region's population has a higher than the national average proportion of Māori – over 50% in some areas – and maintains strong ties to both Māori tradition and the
iwi and
marae structure. The predominant iwi are
Ngāti Porou,
Rongowhakaata,
Ngāi Tāmanuhiri and
Te Aitanga-a-Māhaki.
2007 earthquake At 8:55pm (NZDT) on 20 December 2007, the Gisborne region was hit by an earthquake of

central business district and others experiencing some structural damage. One death was reported (a heart attack of an elderly woman, sustained during the quake) plus minor injuries.
