Najib said his wish of seeing the bodies returned to their families before Eid al-Fitr was not possible due to technicalities involved in the DNA verification process.
He said it was crucial the identification process was done in accordance with strict procedures to ensure evidence would stand up in the course of legal proceedings against the perpetrators behind the incident.
He also expressed anger that international investigators were still unable to have full access to the crash site, adding that he would hold talks with Ukraine authorities on the matter.
Najib spoke to reporters after signing the condolence book at the Netherlands Embassy.
