Hello
Sorry to hear that, it depends on what you mean by assulted, violence or other.
I live in england so I dont know how it works in NZ,
You could go to or phone Hospital Emergency, and ask if they have any numbers for people to talk about what you have been through.
Even the front desk of the police, even if you dont want to report it, they may have helpline numbers.
If you have the Samaritans in NZ you could call them.
If it has seriously affected you, you may want to consider counciling, sooner rather than later is best.
Try and eat , stay warm, and sleep if you can.
Take Care ....... boB
