The recent arrests bring the number of people charged in Operation Inca to 10.
Operation Inca is the National Organised Crime Group investigation into corruption in harness racing.
Today's arrests were the result of a further six search warrants conducted in Christchurch this morning, taking the total number of search warrants to 17, police said.
