There'll be demonstrators outside Auckland High Court today, angry at the justice system's treatment of rape cases.

They want better funding for rape crisis services, prevention and awareness programmes in schools and the reinstatement of a Law Commission review.

Spokeswoman Jessie Hume says people are angry and frustrated at the small number of rape cases which make it all the way through the courts.

"Normally it's about one out of every 100 people who are attacked to actually see justice upheld through our current system."
