Paula Bennett's suggestion some Kiwis have "fewer human rights than others" has been described by her boss as "not an accurate reflection" of National's hardline new gangs policy.

Ms Bennett made the comment on Sunday while she and Prime Minister Bill English announced an $82 million plan to fight methamphetamine. It includes new powers for police to enact searches without a warrant.

"It probably does breach the rights of some of those criminals but they have to have had a serious violent offense behind them already and a firearm charge and on the basis of that we are going ahead with it," Ms Bennett said.

Asked if she believed criminals had human rights, Ms Bennett said "some have fewer human rights than others when they are creating a string of victims behind them".

She later said on Twitter "scum gangs that peddle drugs don't deserve protection".
