The Blues squad includes 12 current or former All Blacks and two Samoa World Cup players in their 38-strong squad that comprises seven rookies.
Strong performances in 2020 led to Alex Hodgman, Akira Ioane, Caleb Clarke and Hoskins Sotutu progressing to the All Blacks for the Bledisloe Cup and Tri Nations campaign to join fellow Blues players Karl Tu'inukuafe, Ofa Tuungafasi, Blues captain Patrick Tuipulotu, Dalton Papalii, Rieko Ioane and newly signed Nepo Laulala. Ray Niuia, who missed the 2020 season with injury, and Auckland prop James Lay were both in the Manu Samoa team in the 2019 Rugby World Cup.
The rookies include sought-after teenage talent, Jacob Ratumaitavuki-Kneepkens (Taranaki), Sam Darry (Canterbury), Taine Plumtree (Wellington) and the Auckland quartet of Soane Vikena, AJ Lam, Zarn Sullivan and Lay.

Bryn Gatland's decision to sign with the Chiefs for the next three years was made without the input of his father.
Warren Gatland will leave his post as Chiefs coach for a year to lead the British and Irish Lions in their series against the Springboks. He will return to the Super Rugby franchise in 2022 for the final two years of his contract, with Bay of Plenty coach Clayton McMillan taking over for the 2021 season.
The 25-year-old Gatland will make up a third of the Chiefs first-five contingent for the 2021 Super Rugby Aotearoa season, being joined by Kaleb Trask and the uncapped Rivez Reihana.
Brodie Retallick's sabbatical means the locking group is rather thin, with 21-year-old Naitoa Ah Kuoi and 20-year-old Tupou Vaa'i the most experienced options.
The team's bulk of class resides in the loose forwards, with Sam Cane, Lachlan Boshier, Luke Jacobson, Pita Gus Sowakula and Mitch Karpik on the books.

Hookers: Nathan Harris, Bradley Slater, Samisoni Taukei'aho

The Hurricanes will have plenty of experience among the ranks, including All Blacks Dane Coles, Tyrel Lomax, Asafo Aumua, Peter Umaga-Jensen, Ardie Savea, Jordie Barrett and Ngani Laumape.
Julian Savea also makes his return to the side, following his return from France and a stand-out season for the Wellington Lions.
Hawke's Bay's Lolagi Visinia and Wellington's Pepesana Patafilo will take up the final two spots in next year's Hurricanes roster.

The Crusaders will be without three key backs to kick-off Super Rugby Aotearoa 2021, but an injection of youth should help cover the losses.
All Black Braydon Ennor will miss the entire competition with an ACL injury he suffered in September. Fellow international George Bridge along with Manasa Mataele will miss the first half of the competition, both with pectoral injuries.
Coach Scott Robertson says they have plenty of depth to lean on, something you need if you want to win titles.
"Braydon's out for Aotearoa, and Bridgey and Manasa are out for half… we're lucky we've got some great depth that can come in.
"We've got a lot of guys that can play in multiple positions like a Dave Havili and Leicester Faingaanuku.
"Leicester during Mitre 10 Cup was carrying a few people out the on the field, he's an awesome talent. If you want to win championships you need depth and if George is out, Leicester comes in. There's great completion in all positions."
The four-time defending champions welcome rookies Isaiah Punivai, Chay Fihaki, Taimati Williams and Fletcher Newell, who have all come through the academy and provincial rugby to earn spots.
Crusaders' 2021 Super Rugby squad:
Props: Michael Alaalatoa, George Bower, Ollie Jager, Joe Moody, Fletcher Newell, Isi Tuungafasi, Tamaiti Williams

There are six new faces and two returning players among the Highlanders squad. The squad features 22 forwards and 17 backs and will again be co-captained by Ash Dixon and Aaron Smith.
A returning familiar face is former All Black Liam Squire who last played for the team in 2019 and has been back in NZ rehabilitating an injury after a brief stint playing in Japan, he is expected to be back to full fitness by the time the competition starts in February.
The big loose forward at full fitness will add some punch to an already exciting looking set of loose forwards with the exciting Japanese World Cup player Kazuki Himeno included along with former Crusader Billy Harmon and James Lentjes returning from injury after missing Super Rugby Aotearoa in 2020.

By the numbers
193 contracted players have been named across the Blues, Chiefs, Crusaders, Highlanders and Hurricanes with the Blues and Chiefs each still to add one additional player.
There will be 13 sets of brothers across the five squads, but only three sets play for the same team – Lachlan and Kaylum Boshier (Chiefs), Ardie and Julian Savea (Hurricanes), and Akira and Rieko Ioane (Blues).
The other brothers are Scott and Jordie Barrett (Crusaders & Hurricanes), Peter and Thomas Umaga-Jensen (Hurricanes & Highlanders), Ofa and Isi Tuungafasi (Blues & Crusaders), Jack and Josh Goodhue (Crusaders & Blues), Ngane and Isaiah Punivai (Highlanders & Crusaders), Bailyn and Zarn Sullivan (Chiefs & Blues), Jackson and Connor Garden-Bachop (Hurricanes & Highlanders), Sione and Tevita Mafileo (Chiefs & Hurricanes), and Daniel and Anton Leinert-Brown (Highlanders & Chiefs).
Auckland hooker Soane Vikena, who joins the Blues at 19 years, five months and one day old, more than 17 years younger than the oldest contracted player - two-test All Black lock and newly minted Highlander Bryn Evans.
Evans (Hawke's Bay), who has previously played for the Blue and Hurricanes, returns to Super Rugby for the first time since 2009. Otago prop Josh Hohneck (Highlanders), and Hawke's Bay wing Lolagi Visinia (Hurricanes), also return to Super Rugby Aotearoa after lengthy absences overseas.
