Elina was given a nine-month suspended sentence for intimidating Hayley-Ann and earlier this year, Coroner Wallace Bain called for law changes to cover cyberbullying in his findings on Hayley-Ann's death.
Ms Collins said although Tuimalu was prosecuted, sometimes it was important to have specific offences rather than use the more general provisions of the Crimes Act.
She would consider the Law Commission's report before making any decisions and expected there to be different levels of enforcement depending on the scale of bullying.
"But if someone is inciting suicide, that is clearly something, in my view, that would end up in the Crimes Act," Ms Collins said.
She said there were ways of dealing with young people who cyberbullied, including through the Youth Courts.
"I think it's about time we took this seriously. We are talking about kids who are suiciding on this, and we, I think over the years we've gone through phases of not talking about suicide.
"I think we are now wanting to talk about it, and how awful it is - their entire families, all their friends are all devastated by this - this is intergenerational damage that occurs."
She said before the internet age, there were options to deal with bullying by changing schools or expelling bullies.
However, technology now meant it was almost impossible to escape.
