The 32-year-old has made three lineout steals, trailing only Shields and Chiefs player Michael Leitch.
Piutau, 23, who will join Irish club Ulster next year, has been a constant threat in the backs for the Blues this year. He has made the most carries in the competition (105) of any New Zealand player - in any position.
And he ranks fourth in metres gained with 708, behind only Highlanders wing Waisake Naholo (855), Julian Savea (746) and Chiefs back James Lowe (745).
Piutau has also beaten 31 defenders, which is good enough for fifth in the competition and behind only Savea (34) and Naholo (33) among Kiwi players. With 15 offloads this season, Piutau has made the 13th-most in the competition.
It all goes to show that Blues coach John Kirwan has some notable holes to fill as his side look to add some respectability to their campaign.
On the subject of offloads, Chiefs midfielder Sonny Bill Williams has joined Waratahs fullback Israel Folau at the top of the pops with 27 this season.
The Hurricanes showed in their win over the Crusaders on Saturday how dangerous a team can be when they promote the ball at pace as they racked up four tries during their 29-23 win.
One of their most influential players this season has been fullback Nehe Milner-Skudder, who announced yesterday he had re-signed with the Hurricanes until the end of 2017. The Manawatu 24-year-old averages 10.2m per carry, the second-most among all fullbacks in Super Rugby. He also averages 3.3 defenders beaten per game, which is the third-best mark.
One more thing
Goal-kicking continues to dog New Zealand players. Crusaders pivot Colin Slade missed two penalties during his side's loss to the Hurricanes on Saturday night, which could have swung the contest considering they lost by only six points.
Chiefs youngster Damian McKenzie also missed a late conversion that could have helped his side avoid a 16-15 defeat to the Rebels in Melbourne last weekend.
