The Maori Internet Society is taking aim at a new wave of cybersquatters.
Chairperson Karaitiana Taiuru says problems are emerging not just in Maori but in the new top level domains.
He says names are being hijacked either for what seem to be racist motives or to hold iwi for ransom.
A Christchurch beauty salon is the registered address for Ngai Tahu for kiwi.nz, and a Lower Hutt man has the Ngapuhi, Tainui and Tuhoe names in the kiwi.nz domain space.
Mr Karaitiana says when a Hamilton businessman bulk registered Maori and Iwi names in the new Maori.nz domain space back in 2002, the society got an apology and the names gifted to the affected iwi.
He says this time the society has issued proceedings to get several names cancelled, and it is advising iwi on how to protect their identity or trademarks online.
