Atkinson now has nearly six weeks without any official matchplay before leaving for Australia.
"There is nothing officially planned for us (NZ under 23) before we go to Aussie that I know of - no camps or anything. I'll just have to keep my skill level up myself. That long without games does make it harder, but we'll just have to make sure we keep training by ouselves."
The 21-year-old, who came back from Auckland to represent Wanganui in the Central tournament this year and still plays for the Central Mavericks in the National Hockey League under region of origin, will be one of five midfielders in the new look national side.
The 20-man New Zealand U23 team will consist of 10 players who are Under 20, thus eligible for next year's Junior World Cup, plus five players in their final year of Under 21 and five more, including Atkinson, aged 21-23.
Atkinson made the 30-man wider Junior World Cup squad in 2013 while still playing club hockey in Wanganui, however missed selection in coach Grant Edwards' final 18 to go to India.
Since then, he has moved up to Auckland to play club hockey and had set his sights on trying to break into New Zealand senior development team.
Therefore, he welcomed the creation of another tier of youth squad for this Australia series, which will help players underneath the bubble of national selection to keep motivated and working after they turn 21.
