Troops and other emergency personnel were deployed in both countries to help with relief operations, with boats and helicopters being used to reach stranded people.
Incessant rains in Pakistan have killed at least 128 people over the past three days and damaged thousands of houses, NDMA said as authorities put four districts on red alert for floods.
And in neighbouring India, torrential rains and flooding have left more than 100 people dead and marooned thousands more, according to officials.
Prime Minister Nawaz Sharif chaired a high-level review meeting Saturday and ordered acceleration of relief and rescue efforts in the country, his office said.
In worst-hit Punjab province, the death toll from rains and flooding over the past three days hit 55 while 235 people were injured, rescue services director general Rizwan Naseer, told AFP.
Another 48 people have died in Azad Jammu and Kashmir, said Akram Sohail, chairman of the disaster management agency in capital Muzaffarabad.
Three soldiers also were killed in a mudslide Thursday near the Line of Control.
Pakistan has been swept by deadly monsoon floods for the last four years -- in 2013, 178 people were killed and around 1.5 million affected by flooding around the country.
Rescue workers struggled to reach remote mountain villages in Pakistan's scenic Neelum valley along the Line of Control but landslides hampered efforts.
"The landslides caused by rains have damaged 4,000 houses in Kashmir -- more than half have been destroyed," Sohail said.
Hardest hit on the Indian side was Indian Kashmir where the heaviest rains and flooding in at least half a century have claimed at least 86 lives since last Tuesday.
"The floods have caused a lot of damage," Indian home affairs minister Rajnath Singh said after being driven around Kashmir's main city, Srinagar, by state chief minister Omar Abdullah.
"If this is the condition of city, what will be the situation in rural areas?" Singh asked.
Many key roads and the lone highway linking the Kashmir region to the Indian plains were closed, communication lines and railway services disrupted, while several bridges were washed away.
Some 27 bodies were pulled from a river in the mountainous Rajouri region of south Kashmir, a senior state official said. The victims were among over 60 people aboard a bus swept into a gorge last Thursday by fast-flowing flood waters. Another 36 people on the bus remain missing.
"Apart from the bus victims, 48 people have died in flooding incidents in the Jammu region (in the south of Indian Kashmir)," said Jammu divisional commissioner Shantmanu, who uses only one name.
Another 11 people were killed in the Kashmir valley as rescuers struggled to move thousands of people stranded by floods to higher ground, officials said.
The usually slow-flowing river Jhelum, which meanders through Srinagar, is running far above the danger levels, swollen by pounding rains.
In India's Punjab state, at least 21 people died as a result of house cave-ins and landslides.
Most deaths were reported from villages near Amritsar, home to the Golden Temple Sikh shrine.
Eight members of one family died in their sleep when the roof of their dilapidated home collapsed, administration official Rohit Gupta told AFP.
In Pakistan, rescue official Naseer said waters were receding in many areas of Punjab provincial capital Lahore and other districts.
But "a red alert" has been issued in four districts -- Jhelum, Sialkot, Nankana Sahib and Narowal -- where the situation was still precarious, he said.
Army rescues 970 people trapped in floods
The army said on Saturday that it had rescued as many as 970 people trapped in flood waters in low lying areas of Jhelum, Srialamgir Sialkot and Qadirabad.
The army rescue teams used five helicopters and 105 boats to evacuate people.
Army troops have also been put on alert at head Trimoo and Panjnand.

Mr.Nawaz I thought you said Punjab will be Paris?
Looks like Venice, better get Metro Boats since Metro Buses are floating into the pit.
I salute cannot bow before Malik Riaz? Yesterday at some tv channel I heard the news that our Real Estate Tycoon Malik Riaz has donated very hefty money in millions (don't remember figure) for those who are affected with floods. He has also sent 2000 tents in addition to food, medicine and cash etc which he had done before also. But regretfully none else came forward though there are many Pakistanis (holding their names) who are listed amongst the richest in Asia but not a single soul came forward.

@Timorlane: Trying to score political points based on a weather related tragedy is hitting below the belt. In terms of good governance, just ask yourself which province is the most stable, developing and attracting foreign investment in Pakistan. The answer is Punjab due to the efforts of Shahbaz Sharif.
This is Sharif Family's fifth provincial government in Punjab and the province sure presents the true picture of its "good governance" after so many ruling stints that stink flood of incompetence
America is with Nawaz.......but Allah is not.
