https://www.crimestoppers-nz.org/speak-up/its-anonymousThrough Crimestoppers reports are made anonymously and the fact it is anonymous is not considered bad in any way.
"What we mean by anonymous
Anonymous means no-one will ever know you contacted Crimestoppers to pass on information about crime.
We know our guarantee to never ask for your name or record your call is vitally important to you.
It makes it easier for you to come forward and break the silence around criminal activity.
Anonymous means
You will never be asked for your name.
Your call will not be recorded.
Your call or secure online web form will not be traced.
You will not have to make a statement to the police.
You will not appear in court.
We create a report from the information you give us. Our call takers will make sure it contains nothing that might identify you, eg if the call is about your neighbour we will not mention this. We don’t even make a note of your gender.
We understand how hard it can be to call, which is why all our call takers are trained to help you tell us everything you know.
We pass on any useful information to the relevant authorities, making sure your identity cannot be discovered."
So we have two views but the major difference is one is an anonymous report to a policing agency and the other in a personal situation.
