Two major ways that Māori have combatted colonialism is through religious movements and protest movements. Both of them, although similar, also have their differences.
Similarities between these movements include:
Focus on upholding Te Tiriti o Waitangi
Occupations as a form of protest (Parihaka, Takaparawhau/Bastion Point, Raglan Golf Course)
Pantribalism
Focus on preserving and/or restoring Māori culture and sovereignty
Differences between these movements include:
Religion as a form of mobilisation (Pai Mārire, Ringatu, Parihaka, Rātana) versus not (Ngā Tamatoa, 1975 Māori Land March, 1970s Land Occupations, "Haka Party" incident, fiscal envelope protests, 2004 Foreshore and Seabed Hikoi)
Use of marches as a form of protest by non-religious movements
Different methods of engaging with the Crown: Te Kooti fought them, Pai Mārire tended to avoid them, Rātana formed an alliance with Labour, and modern protest movements have engaged directly with the Crown to have their voices heard
Engagement with Pākehā: religious movements tended to leave Pākehā alone, whereas protest movements (especially the likes of Ngā Tamatoa and those involved in the "Haka Party" incident) tended to engage with them directly to challenge the status quo
