"The players we have brought in have a lot of potential and the ability to learn and grow quickly. They will add enthusiasm to our group and have the character and work ethic that we are after," said Bunting.
"The idea of training contacts is to support these younger players to migrate into the full squad. There is a big gap between national and international level, so we are looking to give them support to get physically ready and grow their technical skill set."
Bunting said the aim was to not only grow his squad but work closely with the development programme as well.
"The plan this year is to give all of our contracted players experience on the field at some stage. Commonwealth Games and World Cup will be our top players, but we want to inject others throughout the year and have 20 players that are capable of competing for the playing 12 every tournament.
"Beyond that we really want to grow the depth, we want to see the development squad players challenging for contracts and have a good group of 30 players pushing for spots."
The squad is now preparing for April's Commonwealth Games in Australia, before three World Sevens Series tournament and the Rugby World Cup Sevens round out the season.
