Ruapekapeka Pā

Ruapekapeka, a pā 20 kilometres southeast of Kawakawa in the Northland Region of New Zealand, is one of the largest and most complex pā in New Zealand; Ngāpuhi designed it specifically to counter the cannon of British forces.

The earthworks can still be seen.

Ruapekapeka was the site of the last battle in the Flagstaff War of 1845-1846, fought between Colonial forces and the Ngāpuhi led by Hone Heke and Te Ruki Kawiti. This was the first major armed conflict between the Colonial government and the Māori.
