Whale is one of the Taihape team that won the Wanganui Club Sevens two weeks ago along with Tyler Rogers-Holden and Kameli Kuruyabaki, while Samu Kubunavanua and Sheldon Pakinga-Manhire were in the Ngamatapouri side which made the final.
Grayson Tihema, named Wanganui's sevens player of the year for last season, Poni Deni and Clive Stowers complete the lineup.
Having coming fifth at last year's Central 7's by winning the Plate competition to qualify for the national sevens in Rotorua, Wanganui have been seeded fifth in Pool A against top seeds Wellington and fourth seeds Poverty Bay.
Poverty Bay was scheduled to be the third game, however they have now pulled out, meaning Wanganui must try to conjure a victory against Wellington or Hawke's Bay to try and qualify for the championship semifinal for an automatic berth to Tauranga.
In the other pool are Taranaki, Manawatu, Wairarapa Bush and home side Horowhenua-Kapiti.
"The first two teams of each pool will go through to nationals and play for regional championship," said Wanganui manager Darrell Robinson.
"Remainder will playoff for final spot for nationals [in Plate], so the third team on Pool B will go straight into final for last spot, others will play off to meet them."
So, if expected Wanganui can't beat either of their pool mates from the Mitre 10 Cup unions, they will have two sudden death games, likely against Wairarapa Bush and Horowhenua-Kapiti, to get that final qualifying spot, with one of those two teams having a rest and watching the other two in the sole Plate semifinal.
Wanganui played a Wellington rep team at the Piri Weepu Invitational Sevens in Wainuiomata last weekend, losing 26-10, although that possibly was not Wellington's strongest team as several players turned out for the other squads at the invitational.
The matches will be streamed live on the Central 7's Facebook page.
The National Sevens has been moved this season from it's traditional spot in mid-January back to December 15-16 in Tauranga.

Matthew Ashworth (c), Brent Landers, Samu Kubunavanua, Desmond Tyrell/Patrick Parker, Clive Stowers, Grayson Tihema, Dane Whale (vc), Sheldon Pakinga-Manhire, Ryan Karatau, Tyler Rogers-Holden, Kameli Kuruyabaki, Poni Deni.
