Having given homeboy Israel Dagg a chance to redeem himself on Saturday night in Napier at the expense of right winger Cory Jane, they will have to decide who will go from the three others against the Springboks.
Will it be Jane again?
Foster said provincialism counted for nothing when it came to selection when a city hosted a test match, but after the rousing turnout and support for Dagg at McLean Park will Jane be back in the starting XV?
Dagg showed he can hoof a ball down the park under duress and try to keep to the script.
It was far from a perfect display but a hug of approval from Hansen after the game spoke volumes.
Dagg fumbled the ball once and overcooked a try-scoring opportunity to Ben Smith as his pass went begging over the right winger's head.
Smith had a quiet day on Saturday against the Pumas but with his ability to step off either foot in Christian Cullen fashion can the ABs afford to keep him out of the equation?
Hansen was forthright at the media scrum.
"Yes, I have some ideas but I don't want to reveal everything to the Springboks right now, do I?" he responded with a grin.
Point taken, but the Boks and the Cake Tin will pose a different range of challenges.
No doubt, Shag and Fozz will have considered that as well with all the other permutations.
For Dagg, Smith and Jane versatility also kicks in.
At McLean Park, No3 first five-eighth Beauden Barrett struggled with his conversions and penalties, but it was surprising that the ABs stable didn't opt to use Dagg, who was practising his kicks on the eve of the test with bench pivot Colin Slade.
Heavy underfoot, it made perfect sense, although the degree of accuracy with Slade may have been the difference.
Slade missed his first of three and Barrett's four from five was a glaring C in a glowing report card.
But when you have Aaron Cruden and Dagg as kickers then is it worth sacrificing the explosive running Barrett brings to the backline?
Besides, the inclement weather was always going to be a factor so in many respects it's difficult to make too many sound judgments on anything except that some players adapt to testing conditions better than others.
Hansen has talked up Jane, who didn't hit his straps until the Wallaby walloping in Auckland in the previous round.
It's possible Malakai Fekitoa, who didn't get on the park at all on Saturday, may be the sacrificial lamb if, the good lord forbid, Ben Smith were to slide to the bench as a utility.
The forecast in the capital looks promising with sunny but wintry temperatures, although the swirling winds will make it interesting considering the Boks have wingers who are a different breed from the Argentines.
For now though Hansen isn't amused with the antics of streaker Rose Kupa who ran on to McLean Park in the 74th minute in her birthday suit to tick an item off her bucket list with a slap on Dagg's rear for good measure.
Never mind the bells and whistles on display, much to the amusement of the sellout crowd, Shag emphasised the security of his players was of utmost importance.
"You can't have lunatics just run on to the field like that to ruin the game.
"How did she get there with so many red jackets around?"
Labelling streakers a "pain the backside", he felt the security staff needed to act much quicker.
It's a fair point and one that has been tested in Hawke's Bay before.
Frankly, none of the red jackets around the perimeter of the park looked like they could keep up with the woman, who once made it into the Hawke's Bay Tuis trial squad. My initial reaction was if this woman isn't playing club rugby then she should be.
Jokes aside, it did detract from the game although grinning ABs captain Ritchie McCaw said they noticed her but she wasn't a distraction as such.
In 2011, a male streaker hopped on to the racing track in Hastings during the JB Organics Hawke's Bay Spring Racing Carnival.
None of the red jackets was able to keep up with him, opting to tackle him at the finish line as one would a spent thoroughbred.
Ironically the security staff at the Graeme Lowe and Centennial stands didn't look like running.
Those at the HQ building and Harris Stand corner moved towards Kupa but then opted to unload a hospital pass to the embankment corner.
It appears there's an urgent need to employ fit security officers.
Problem solved.
