"Why has it taken the loss of two more of our tamariki, to be taken away from us, before anything is done? There needs to be some guidance and co-ordination," said one woman.
"Collectively, as a voice, we can make this happen. There has to be something to look after our young, to look after the young leaders of tomorrow."
The tangi for the second girl was held yesterday morning, when tributes and messages of love continued to flow from friends and family for the teenagers.
The Ministry of Education is also providing support to the school in the form of a specialist team.
One of the girls died last Monday and the other died on Saturday. It is believed no foul play is suspected.
The group also said that the family of one of the girls was "shocked" and "disgusted" to find both girls named with Facebook photos in yesterday's Dominion Post.
