The O-League newcomers didn't find the equaliser until the 79th minute through leftback Ian Hogg's left-foot volley following a freekick in the tempestuous affair with players exchanging a few handbags.
More controversy as Hauata awarded Auckland another penalty in the second spell of extra time after Hogg was deemed to have handled a Ryan de Vries shot. This time O'Keefe, who also parried a penalty shootout bid, denied Darren White. Wellington centreback Chris Bale was sent off for "going off at the referee".
"Team Wellington certainly didn't think so [penalties awarded]," says Robertson after teammates Luis Corrales and Hogg missed in the shootout.
The Capital side have reconciled the loss as "a good achievement in their first attempt".
Robertson enjoyed the "tough tourney" but "would have enjoyed it more had we won the last game".
He lauded the hosts but felt the turnaround time between games was testing although the weather was no different to the national summer league here.
Auckland will travel to Japan in December to improve on their incredible third-place finish last year.
On that occasion they brought home $3.22 million in prizemoney.
