Rickard rallied support for the land to be returned to local Māori during the 1970s, culminating in an attempt to reoccupy the land in 1978. She was among several arrested at the site during a peaceful sit-in.
The campaigning of Rickard and her supporters had a successful end. The disputed land was later transformed into a farm, complete with a training centre and a marae.
Rickard also led a hikoi to Parliament in 1984, which called for an end to Waitangi Day celebrations until all outstanding Treaty of Waitangi grievances had been settled.
She also stood for Parliament for the Mana Motuhake Party and later formed her own party, Mana Māori.
