The jet MASM.KL Flight MH370, which vanished with 239 people aboard, could hypothetically have reached the Central Asian nation's air space, but it would have been detected there, the Kazakh Civil Aviation Committee said in a detailed statement sent to Reuters.
Malaysia Airlines planes had made nine regular flights to and from Europe over Kazakhstan's territory on March 8, the report said.
"Even hypothetically thinking, before reaching Kazakhstan's territory this plane would have had to fly over other countries along its route, where the flight zone is also closely monitored, so we would have received information from these countries," the report added.
As of now, searchers strongly suspect that the jet has been hijacked or sabotaged. Doubts hardened further when officials said on Sunday that the last radio message from the plane - an informal "all right, good night" - was spoken after the system, known as "ACARS", was shut down.
Malaysia Airlines chief executive Ahmad Jauhari Yahya said on Monday that it was unclear exactly when one of the plane's automatic tracking systems had been disabled, appearing to contradict the weekend comments of government ministers.
