The Bay of Plenty, often abbreviated to BOP, is a region in the North Island of New Zealand situated around the body of water of the same name. The bay was named by James Cook after he noticed the abundant food supplies at several Māori villages there, in stark contrast to the earlier observations he had made in Poverty Bay.
The geographical bay is defined by 259 km of open coastline used for economic, recreational and cultural purposes. The coastline from Waihi Beach in the west to Opape is defined as sandy coast, while the coast from Opape to Cape Runaway is rocky shore.
Prominent mountains in the region include Mount Maunganui, Mount Tarawera and Mount Edgecumbe/Putauaki, which also have cultural significance to local Māori. The Kaimai and Mamaku mountain ranges lie at the western border of the region. Swamp land was formerly concentrated around a number of rivers in the region, but much of this was dredged in the early part of the 20th century to increase land for settlement and other uses.
