People charged with murder, P-dealing and some sexual and violence offences would find it harder to be freed on bail under proposals by the Government.
A bill to change the rules around granting bail, to be introduced to Parliament early next year, would also make bail more difficult for young adults aged 17 to 19 who have already served time behind bars.
Prime Minister John Key said although defendants were innocent until proven guilty, too many committed crimes while on bail. "There are some people that are currently getting bail that we don't believe should ... they present a risk to the community."
At present, the prosecution has to prove an accused is a risk to public safety to have bail denied.
Under the new law, for certain offences the defence would have to prove the accused is not a risk to public safety or interfering with witnesses or evidence that would affect their trial.
