New Zealand reached the World Cup for only the third time with a 3-0 win over New Caledonia on Monday but lost Nottingham Forest striker Chris Wood to injury.
The All Whites join already qualified Japan and co-hosts the United States, Canada and Mexico at next year's finals thanks to three second-half goals.
But the victory in Auckland in the final of Oceania qualifying came at a cost, with in-form skipper Wood suffering what appeared to be a hip injury.
Soon after half time at Eden Park, Wood hurt himself swivelling for a shot and required treatment before hobbling off in the 54th minute.
