On a personal note, Wood was relieved to get through his short stint.
"[It felt] all good, fine," said Wood of his hamstring. "It was feeling good out there so I am feeling good, confident."
Wood almost made an immediate impact, as he came on just as New Zealand were awarded a free kick 25 metres from goal, a similar range to his memorable strike against the Solomon Islands in September.
He hit it well, forcing a good save from the Peruvian keeper, before the referee ordered a retake, which Wood blasted into the wall.
Wood had hardly trained throughout the week - coach Anthony Hudson admitted they had been nursing him through - and so his benching wasn't a last minute call.
"[The decision] was made," said Wood. "They knew I could do a job coming off the bench. [Now] we have to wait and see, see how it settles down."
Wood, like most of his teammates, played down the result, emphasising that the job is far from done.
"It was a good result, it wasn't too bad," said Wood. "It leaves it all open so it wasn't too bad."
