When Rangiriri pā was taken by General Cameron after a white flag of truce was flown, Cameron informed Māori that Governor Grey would only come to talk peace if his forces were allowed to enter Ngāruawāhia unopposed. Cameron entered a deserted Ngāruawāhia on 8 December 1863, but Grey never came to talk peace. Despite Māori protest, sales of confiscated land went ahead in 1864, shortly after the invasion. During the 19th century, Ngāruawāhia was named Queenstown and then Newcastle. However, the town returned to the original name in 1878.
