National MP Simeon Brown has allegedly received more threats from the Mongrel Mob after criticising the gang on Twitter.
Leader of the Opposition Judith Collins said on Wednesday morning Brown has gone to the police again after threats were made against his life.
She told The AM Show gang members sent Brown death threats after he tweeted it was "unbelievable" that gang members were able to "take over the road" for a tangi in Hawke's Bay.
Asked whether Brown was safe, Collins said she "hopes so".
"He's concerned - as am I... they used words like, they said they would 'pop him' - which I think that means to shoot him."
Brown told Newshub he received "a number" of threatening messages on Tuesday night, which he has taken to the police.
"They've taken it seriously - I'll be going in later today to give further information."
One man has already been arrested for allegedly threatening to kill Brown. The 25-year-old was found at a Lower Hutt address in early May and entered no plea when he appeared in court.
Brown is National's spokesperson for police, Corrections, the Serious Fraud Office and youth.
The MP said he initially received death threats after criticising Green Party co-leader Marama Davidson's visit to the Hamilton Mongrel Mob.
The 30-year-old had also previously called the Mongrel Mob "scaredy cats" for cancelling an opportunity to submit on his Firearm Prohibition Orders Bill.
