Mr Rodger was one of six recruits who attended a pre-college farewell at the Northland District Headquarters in Whangarei.
It is one of the bigger Northland contingents sent to college in recent years.
Mr Rodger, of Ngati Hine decent, is relishing the chance to begin his training but is under no illusions.
"I expect to tested, challenged and fail and to find a way to achieve. That's what got me here."
Recent graduate Constable Shawny Hokai spoke to the recruits and gave them an insight into college life.
She graduated last October and, after a five week stint in Kaikohe, has been posted to Kaitaia.
With strong links to Whangape, the 24-year-old said she loves policing in a rural community.
"I love policing where I am from and going back to my roots and helping in the community and helping families. Working in the rural environment it makes you feel like you can make a difference for someone."
She left school at 16 and went farming but was drawn to policing by the camaraderie, the prospect of better work stories and the variety.
In three months on the beat she has attended a suicide, burglary, domestic disputes, crashes, robbery and a pursuit.
"People look to you to have the answers and in stressful situations you have to think on your feet. You always have to remember you are dealing with someone's family in good and bad situations."
Northland police recruiting officer Sergeant Shelly Hill said police wanted to recruit people who reflected Northland's communities.
Recruiting locally and having officers return to the area they knew was a huge benefit.
