Ardie Savea played No8 against Samoa this year when Read was unavailable, Sam Cane has deputised during games, Liam Squire can do the same and Akira Ioane could help during a bloodbin or sinbin timeout.
The 26-year-old Whitelock brings a sensible package of leadership, knowledge about the game and reliable skills which have been a cornerstone for Canterbury and escalated at the Highlanders. He has been in the All Black inventory since 2013 when he went to Japan and Europe but has not featured again until this trip.
He is ultra-reliable whose value is measured in workload and low error rate rather than a flashy offload or starry move in much the way that Brad Shields brings consistent value to Wellington and the Hurricanes.
He has failed to light the national selectors' wick and Whitelock seems to be in that marginal territory, too. Look around though and the specialist No 8 options are not plentiful and perhaps it's time for the All Black selectors to "suggest" a few ideas to the Super Rugby staff.
They've already talked about Scott Barrett needing to put on a few kilos to bulk up his impressive work at lock and he has played blindside where he is comfortable with the ball and on defence, traits which could be shaped to life as a No8.
Maori All Black Jackson Hemopo is another hard edge athletic ball-playing lock. So, too, Michael Fatialofa at the Hurricanes where more appearances from Blade Thomson would also push his cause.
