South Africa started the tournament with a real stutter. They were not convincing in beating neighbours Zimbabwe and were convincingly beaten by India in Melbourne. The side-effect of that is that many of their top-order have had opportunities not otherwise afforded to teams that have cruised through the first three weeks of the tournament.
That is not to say that Pollock has remained unmoved by New Zealand. By his reckoning, Brendon McCullum's men have a date with destiny with South Africa at an Eden Park semifinal.
"I'm impressed by what I see," Pollock said. "It's one thing to have a captain who is as positive as you can, but it's not worth much if you don't have the backing of your team and the bowlers in particular.
"It's refreshing to see."
There is a school of thought that the style New Zealand are playing - best summarised as all-out attack - is not sustainable through to the end of a tournament, but Pollock is not buying that.
"The best thing you can do for your quarter-final chances is set yourself up to play the fourth team in the other pool. It looks like New Zealand has done that. Then you just have to be playing your best cricket in the semis.
"If New Zealand's bowlers keep producing like they are, it's absolutely possible to keep playing like this."
South Africa meet Pakistan at Eden Park tomorrow. Pollock think there could be some big totals.
"You see the sublime form of AB de Villiers and on a ground like this... you could see some big scores made."
