Listen: Dion Nash on the Radio Sport Breakfast
Nash, a former selector, said Eden Park and its short boundaries could be very difficult to defend when a batsman like Stoinis got established.
"The boundaries are so hittable...the pressure goes onto the fielding team," he said.
Coach Mike Hesson echoed that, and said the surprise factor with Stoinis - playing his second ODI - made the job tougher.
"He had a pretty poor Big Bash but he's done pretty well in the IPL," Hesson told Mike Hosking on NewstalkZB.
"We knew a little bit about him but we got hit to areas of the park we were a little unhappy about.
"But that's also the nature of Eden Park. If someone gets in and has a bit of power, it is difficult to contain.

"We were in a strong position but of the grounds in the world, if you need 100 off 10 overs Eden Park is the place to have a crack at it."
Hesson was delighted with a victory over "the world's best" and pointed to a record of 11 wins from 11 at home this summer.
"The heart rate was getting high (at the end)," said Hesson.
"Eden Park has has some great spectacles over the past few years. It was a great game.
"Beating Australia is difficult and whenever you do you gain pleasure and confidence."
