Rights groups and politicians have for years called for tougher laws to tackle perpetrators of violence against women in Pakistan and the move follows a slew of high-profile killings in the country.
The perpetrators of so-called honour killings -- in which the victim, normally a woman, is killed by a relative -- often walk free because they can seek forgiveness for the crime from another family member.
A committee comprised of lawmakers from both lower and upper houses of parliament unanimously approved the two bills this afternoon, meaning they could be voted on within weeks.
Law minister Zahid Hamid, who chaired the committee, said: "We have plugged all loopholes in the anti-honour killing legislation, which will be put up for approval at a joint sitting of parliament soon."

Prime Minister Nawaz Sharif's ruling PML-N party has a large majority of seats in the lower house and the bills are believed to have enough backing from opposition parties to pass in the senate too.
But punishment was left to a judge's discretion when other relatives of the victim forgive the killer -- a loophole which critics say is exploited.
According to Hamid, under the new law relatives of the victim would only be able to pardon the killer of capital punishment, but they would still face a mandatory life sentence of twelve-and-a-half years.
In the anti-rape bill, "a provision to conduct DNA tests on both the alleged victim and perpetrator has been added for the first time," he said.
Commenting on the move, Sughra Imam, a former senator from the opposition Pakistan People's Party who first tabled both bills said: "No law will eradicate a crime entirely but the law should be a deterrent. Laws are supposed to guide better behaviour, not allow destructive behaviour to continue with impunity."
Today's development came just six days after Social media starlet Qandeel Baloch was strangled to death by her brother once again casting a spotlight on honour killing murders which claim around a thousand lives in Pakistan every year.
