A powerful expression of identity, the traditional facial tattoos, Moko, practically disappeared in the first part of the 20th century when assimilation was the dominant ideology. Starting in the 60s, they were found again amongst the Maori prison population. Then in the 70s, it became the symbol of activist Maori nationalists. Today, with the renaissance and recognition of Maori culture, Maori university students have also adopted tattoos.
