Police were called to investigate death threats made against Story host Duncan Garner this week over his stance on pit bulls.
Garner says he was sent "revolting and vile threats" over private message on Facebook, after he said pitbulls were "horrible" and should be banned.
One comment read: "You should probably euthanize yourself before publicly humiliating even more."
Another said: "If any pitbull attacks again I hope its [sic] you for your f***** up comments!!!"
MediaWorks contacted police who have since acted; one person has been issued a warning.
Garner said: "I want to thank the New Zealand police for acting so quickly and for sorting this issue out. Everyone is entitled to their opinion but threatening to kill someone as a result is a step too far.
"I won't back down from my views or be shaken by the nature of the threats that came my way - we need these pit bulls banned. We can do more. And we must."
