Coach Ricki Herbert, who will name his team tomorrow, confirmed that Tommy Smith should be available despite a bruised foot, with fellow defender Ben Sigmund also likely to be involved despite a stomach bug.
Herbert said he was wary of changing the line-up too much but admitted he could tinker with his strikers.
Goalscorers Shane Smeltz and Chris Wood, plus Jeremy Brockie, started up front in the recent match against New Caledonia.
"We're considering a couple [of changes]," Herbert said. "I'm not really keen to change a lot. That group had to step out and get the campaign underway [against New Caledonia]. There was pressure on us all to do that and they did it and pretty effectively as well."
There is a feeling that Smeltz at least could be rested, with Kosta Barbarouses, Marco Rojas and Chris Killen other options up front for Herbert, who will come up against striker Benjamin Totori, his recent signing for the Wellington Phoenix.
"Collectively they're a side that will come here pretty confident. They got a good win over Tahiti [2-0], it's up to us now."
Meanwhile, 35-year-old defender Nelsen, said he was enjoying his time at new club Queens Park Rangers. Nelsen has joined his former manager at Blackburn Rovers, Mark Hughes, at Rangers following a one-season stint at Tottenham Hotspur.
"It's great being back with Mark Hughes, I know all the staff there and it's part of a little revolution, the owner is changing a lot of things, it's pretty cool," he said.
"I love London, in hindsight I kind of wish I did it a few years earlier. In saying that, I obviously had an amazing experience in Blackburn but it definitely rains a lot less down south."
