The UNRWA will deliver aid packages to 9000 families on Sunday, spokesman Adnan Abu Hassana told Anadolu Agency.
He added that the rest of the beneficiaries will get their packages within the coming days.
Abu Hassana explained that the aid delivery was delayed a few days over "technical reasons."
"These aid deliveries help impoverished families and would never stop," he said.
The U.N. agency, established in 1949 following the Israeli occupation of Palestine, distributes quarterly food supplies to families that fall below the poverty line in the blockaded Gaza enclave, home to around 1.8 million Palestinians.
It classifies those below poverty line in Gaza into two categories; those with daily income of less than $3 per family member and those with less than $1.5 daily income per family member.
Seventy percent of Gaza's residents are registered as refugees with the UNRWA, with the number expected to rise by 2020.
