In the past 24 hours, more than 122,000 people have been moved from Jalalpur Pirwala, a city in eastern Punjab province, said Irfan Ali Kathia, director-general of the Punjab Disaster Management Authority.
Many sought shelter with relatives while others were staying in relief camps, he said.
In flooded districts, most said they received little or delayed aid.
The government insists it was carrying out rescue and relief operations simultaneously and that truckloads of supplies are sent daily.
Flooding triggered by weeks of torrential monsoon rains, cloudbursts and water releases from dams in neighbouring India had displaced 2.2 million people across Punjab since August, Kathia told reporters.
At least 61 people have died in flood-related incidents since August.
Kathia said Multan, another key city in Punjab, was still at risk of flooding as levels in the rivers continued to rise.
Preparations were under way to carry out controlled breaches of embankments to divert water towards rural areas to protect cities, he said.
"We were able to save many lives through timely evacuations, though some people refused to leave until the water reached their villages," he said.
He said thermal imaging drones were used to find survivors.
Floodwaters had submerged more than 3900 villages in 26 districts since August 23, Kathia said.
According to the National Disaster Management Authority, India on Tuesday again shared river data, noting that one Indian river remained at the danger mark, raising the risk of further cross-border flooding in Pakistani areas along the border.
Nationwide, monsoon flooding since late June has killed more than 900 people, according to the disaster authority.
Nearly 80,000 people are living in relief camps across Punjab, and evacuations also took place in southern Sindh province, where more than 100,000 people were relocated last week.
Sindh was among the worst-hit regions in the catastrophic 2022 floods, which killed 1739 people across Pakistan.
