The Whanganui campaign was a brief round of hostilities in the North Island of New Zealand as indigenous Māori fought British settlers and military forces in 1847. The campaign, which included a siege of the fledgling Whanganui settlement (then named "Petre"), was among the earliest of the 19th century New Zealand Wars that were fought over issues of land and sovereignty.
