He received a favourable assist from the Vanuatu defenders - first strolling in unmarked to tap home a long-throw at the back post, before some defensive self-destruction saw a horror back pass free the Leeds United striker for a simple one-on-one finish.
To characterise the gap in class as a gulf would be doing a disservice to the disparity, as Michael McGlinchey made it 3-0 within 10 minutes by curling a free-kick over a defensive wall consisting the entire Vanuatu outfield.
Also evident were the inaccuracies of the FIFA rankings, which have the audacity to claim that Vanuatu (181) are only twenty spots behind the All Whites.
A shoulder injury to Wood denied him the chance of a rapid hat-trick, while Vanuatu also made an early substitute of the unforced variety, with tactical changes required after just 23 minutes.
By then, a fourth goal had gone in, with Rory Fallon benefitting from another defensive mishap. Fallon - not the fleetest of foot - outpaced out-of-position defenders, rounded the keeper and curled a classy left footed finish into the top left corner.
In celebration, Fallon pointed to the sky, but it was Vanuatu needing assistance from above to stop the rout.
Kosta Barbarouses made it five before the half with a classy finish, but Vanuatu received a respite in the second stanza - perhaps of the statistical, rather than spiritual kind.
Only six shots were required from the All Whites to create the five goal first half - an incredibly unsustainable rate of conversion which regressed in a less clinical second half performance.
While the scoreline was deservedly one-sided, there were moments of uncertainty for the inexperienced All Whites defence. Vanuatu had a clear penalty waved away, wasted a slew of free-kicks and often found themselves in pockets of space in favourable territory.
Those pockets turned to acres in the second half, with All Whites keeper Stefan Marinovic forced into several strong saves to keep a clean sheet as Vanuatu ended with more shots and possession - statistics which will be of concern for Hudson.
The All Whites will face a stricter test against the Solomon Islands in the final group game on Saturday, before the semifinals begin.
