THE AFL integrity unit will grow to 14 employees in 2014, when two new investigators are appointed in coming months.

The new senior investigator and investigator positions to be added to the Competition Integrity Department will be involved in investigations relating to gambling, doping, salary cap, the draft or personal conduct.

The positions were advertised on the weekend.

This bolstered department now sits within the broader Legal, Integrity and Compliance area, having been removed from the AFL's Football Operations department.   

It has increased rapidly since August 2008 when its manager Brett Clothier became the first person employed in the area of integrity.

Soon after the Australian Crime Commission's Drugs in Sport report was released in February 2013, the AFL promised to increase its investment in integrity and has continued to make changes throughout the season.

At the AFL season launch in March, League CEO Andrew Demetriou said he was proud of the way the AFL had responded to the report, "rapidly enacting significant changes to the way we monitor our game, our systems, and our personnel - at all levels."

The AFL also recently announced changes to its Anti-Doping Code, while examining its key rules around 'prejudicial conduct' and the requirements for the registration of staff and officials.  

It is also investing in upgraded technology, which will be introduced during the pre-season, to implement the registration requirements under the new code.
