At the 2019 event in Spain, New Zealand beat Chinese Taipei and China.
An "achievable goal" for this year was to knock over Japan, Fitness said.
"Because of the Covid climate, some teams have been coy on their entries so we are still waiting on the final draw to come out with who is in our pool.
"Generally, in our tier (tier three) there are teams like Uruguay, the USA, Belgium, the Netherlands, India and Japan."
Unlike the senior competition, the junior world champs don't use a tiered system.
Fitness's first taste of international rink hockey came as a junior at the age of 16, lining up against Chile in front of a packed stadium.
"It's like the Ethiopian rugby team playing the All Blacks.
"Funnily enough, we are playing warm-up games there (Chile) before heading to Argentina. I'll be heading back after 20-odd years."
It will be Lockett's first senior world champs and Blinkhorne and Allen's second.
Rink hockey teams are made up of five players on each side.
"I'm guessing Whanganui players will take up two or three positions in the starting lineup," Fitness said.
He said the Whanganui Rink Hockey Club was on the hunt for new players.
"That's male and female of any age and experience.
"We have training and teams to suit all abilities."
