Netball Western Australia is downplaying the threat against West Coach Fever Fever coach Norma Plummer, describing it as idle.
A Dunedin resident made the threats against Plummer late last year via a posting on her personal website.
The matter was referred to Australian police who contacted their New Zealand counterparts, ahead of the Fever playing the Southern Steel in Dunedin last week.
Plummer is refusing to talk to the media about the incident but a team spokesperson says they regard it as a non-event, though they felt it appropriate to contact police given the nature of the threat.
Extra security arrangements have been put in place and the spokesperson says they now regard the matter as having been dealt with.
The West Coast Fever play the Waikato Bay of Plenty Magic in Tauranga on Sunday.
Before joining the Fever, Plummer coached Australia to two world championship wins.
During and after her tenure she raised the hackles of New Zealanders with her comments on same netball issues, including her infamous "bunch of scrubbers" remark about the Silver Ferns, which she later insisted had been taken out of context.
