Last week, delays relating to the airport's traffic control tower were highlighted by MP Stuart Nash.
Nash - Police Minister and MP for Napier - had hit out on Twitter after his flight from Hawke's Bay Airport was delayed.
He claimed the late departure - the second in as many weeks - was because an air traffic controller was late for work.
Nash described the controller as a "clown".
Airways apologised to Nash, also on Twitter and said the delay was due to an "unexpected staff shortage".
"Unfortunately this came after a controller had a car breakdown en route to work last week," a spokesperson posted on the social media site.
"While unrelated, we regret these two issues have inconvenienced passengers."
In an unrelated incident, Eastern Police had confirmed officers were deployed to a reported "disturbance" at the Napier air traffic control tower at 4pm on August 5.
No arrests were made or charges laid as a result of the incident.
It is understood police were called to evict a woman from the air traffic control tower at Hawke's Bay Airport after she became enraged at her husband - the duty controller.
