The two countries have also scrapped visa-free travel for each other's citizens. Malaysia said the group of people with the expired visas were working in Sarawak, one of two Malaysian states on the island of Borneo.
The exiled North Korean was said to have two wives and three children.
The family of the murdered Kim Jong-nam will allow Malaysia to determine what to do with his body, said Health Minister Datuk Seri Dr S. Subramaniam.
Experts say the VX nerve agent used to kill Kim was nearly certainly produced in a sophisticated state weapons laboratory, and North Korea is widely believed to possess large quantities of chemical weapons. That includes a period where the United States has provided $1.35billion (£1.1bn) in assistance to North Korea as an encouragement to take a different pathway.
Zahid also said that the DNA confirmation was obtained after Malaysian authorities went overseas to an undisclosed location, to get the DNA samples from Jong-nam's son.
Seoul's unification ministry earlier said North Korea's "show-off" project targets the privileged class in Pyongyang, not ordinary North Koreans. Malaysian Prime Minister Najib Razak, described North Korea's actions as an "abhorrent" act of hostage taking and banned North Koreans from leaving Malaysia in response. About 315 North Koreans are in Malaysia.More news: Firm declares Ivanka Trump brand is booming
Malaysian newspaper The Star quoted the deputy prime minister as saying that the Malaysian government had not ruled out handing over Kim's body to North Korea to secure the return of nine of its nationals.
Malaysian authorities have verified with a DNA sample that the man who was assassinated at Kuala Lumpur International Airport on February 13 was Kim Jong-nam.
"They have given consent to let the government decide how to deal with the body", Noor Rashid Ibrahim said.
Kim Jong-nam, who was the estranged, elder half-brother of Kim Jong-un, had been passed over for the North Korean succession and was living in the Chinese territory of Macau at the time of his death.
Pyongyang has repeatedly sought custody of the body, but Malaysia has so far refused to release it to anyone other than Jong-nam's family.
Another North Korean, the 30-year-old Ri Ji U, has also been linked to the crime, but his whereabouts remain unknown.
