He then walked around one plane several times and loitered around the wheel assembly. He ran off after a security guard confronted him.
Ndabagera made his way to the terminal building and escaped out into the front car park. Someone found his wallet and passport during a search near the plane.
The defendant told police he had been looking for his cellphone, wallet and passport which had been stolen.
The two assault on police charges related to his actions while in the cells at Tauranga Police Station on May 20.
Ndabagera grabbed a female constable's body armour vest and torch and refused to give it back.
Holding the torch in his right hand, he made punching moves towards the officer with his other hand, and took up a fighting stance, the summary said.
Ndabagera tried to punch a male constable in the face before he threw another punch which connected with the victim's right shoulder.
The officers tried to restrain him, and when the first constable went to handcuff him, Ndabagera kicked out several times striking her lower legs.
The defendant refused to co-operate and had to be forced back in his cell.
Lawyer Tony Rickard-Simms told Judge Paul Mabey QC his client was a French national on a visitor's visa and had been looking for a place to stay.
Mr Rickard-Simms said the Immigration Service has served Ndabagera with a deportation notice and he was due to leave the country by the end of the week.
Judge Mabey, who convicted and discharged the defendant on all four charges, further remanded him in custody pending his deportation.
