Constable Riki Kauika was given the Driver Training and Road Policing Practice Award, while Constable Joshua Kauika took the prize for Physical Training and Defensive Tactics.
"I think they'll make really good policemen actually," Anne said.
The Kauika brothers also have an aunt who was in the police for a few years, based in Taumarunui.
Anne Kauika said Riki probably preferred to be on the beat and he'd want to get a good feel for the job.
"He's probably a quieter man than what Josh is - but in saying that he will be a very good community policeman. Plus he's got a very technical head on his shoulders from all the golf he's played.
"I have no doubt he'll probably end up playing golf for the police as well."
She said Josh's years in the navy meant he would be able to be called upon by the police dive squad if needed.
He has already worked with the police in search and rescue operations.
But, like Riki, it was likely Josh would first do a few years on the beat.
Josh will start his work in Northland while Riki will be deployed to the Central District.
The Kauika brothers graduated alongside 77 other new constables at The Royal New Zealand Police College on Thursday. The new constables are aged between 18 and 50 and began their studies in September.
