Questions around why violent offenders are getting electronic bail.

Police have issued an arrest warrant for Naya Ropiu Fabian Wharekura, who has breached bail conditions.

The 28-year-old has been charged with killing a man in Invercargill last year.

National Party police spokesperson Mark Mitchell says Wharekura should be in prison and not out on bail.

"Because now he's a clear and present danger to the public, and of course he's tying up police resources now in terms of them trying to locate him and arrest him and get him into custody."

Wharekura has distinct face tattoos - including the words Ngaruawahia and Waikato - and should not be approached.
