During the ceremony Commissioner Baki expressed confidence in the promotional changes as they signified the change of the old guard to the new.
He said that these officers represented the future deputy commissioners, and commissioners in the making.
Baki also expressed satisfaction with and endorsed the outcome of the Police Promotion Selection Board 1 of 2015 under the chairmanship of Reverend Sommy Setu, and members Francis Tokura, Chief of the Bougainville Police Service, and ACP Southern Allan Kundi.
These changes, Baki says, captures and supports his intentions for the RPNGC while also signalling the change that is anticipated to take place within the RPNGC to prepare itself for the future.
One of the 12 is Joanne Clarkson, the first female officer to be promoted to the rank of Assistant Commissioner of Police (ACP).
Clarkson says that this was in homage to the brave women who took the initial steps of joining a predominantly male driven workforce.
Meantime, two of the newly promoted ACPs, Nema Mondia and Jerry Frank have served 13 and 15 years respectively as chief superintendents before their elevation.
Frank, who will now be ACP Traffic, says that he is motivated to be in his new post and also congratulated his other colleagues who were promoted today.
