On 25 May 1978, New Zealand police and army officers forcibly removed hundreds of protesters from Takaparawhā / Bastion Point.
It was the end of a 506 day-protest by Ngāti Whatua Ōrakei who sought to retain their land and prevent the government's plans to develop luxury housing there.
On an overcast morning on 25 May 1978, a convoy of army trucks and hundreds of police officers moved onto the land to evict the people onsite, which resulted in the arrest of 220 people.
The protestors were objecting to the government's plan for a housing development there.
Makeshift structures, including the former warehouse building-turned-whare Arohanui, were pulled down.
Whai Ngata visited Bastion Point in 1978 to make an episode of the Māori radio series Te Puna Wai Kōrero.
He interviewed protest leader Joe Hawke about the plight of Ngāti Whatua Ōrakei and the historical narratives of their eviction from their ancestral lands at Okahu Bay.
During the interview, Whai asks about the sacrifices Ngāti Whatua made. He responds that the protest was a collective effort.
The protest action taken by Ngāti Whatua Ōrakei resulted in the first retrospective Māori land claim before the Waitangi Tribunal.
In 1988, the government agreed with the Tribunal findings to return Bastion Pt to Ngāti Whatua Ōrakei along with a compensation package.
This week, Ngāti Whatua Ōrakei hosted a range of activities as part of the 40-year commemorations.
A dawn service was held on Bastion Point, followed by commemorations attended by other iwi.
The Auckland War Museum, Auckland Public Library and Pearce Gallery hosted photographic exhibitions.
