Despite a strong tail wind in the first half, Wellsford only managed 13 points to lead 13-3 at the break.
A quick try from Hikurangi at the start of the second half narrowed the gap to 13-10.
In a change of tempo, Wellsford turned up the heat despite the relatively strong southwesterly breezing in and ran in several well-executed tries to claim the win.
Standouts for Wellsford were fullback Matt Wright - who ran in three tries - and his brother Ross, who made crucial tackles and bustling carries.
"We turned it on in the last 30," Neal said. "We held the ball a lot more. [It was] a relatively strong wind so holding the ball in the second half paid off."
Hikurangi could not replicate their 14-7 win over the Western Sharks in the last round of the competition, as their performance deteriorated after the first 50 minutes of the match.
With two rounds remaining before playoffs, all eyes will be on the standings over the coming weeks.

Wellsford will have a their full repertoire of players returning for the remaining matches, which should see them return to the force they were in the first half of the season.
Old Boys Marist's winning run of late highlights them as serious playoff contenders also. They dismissed Waipu 29-8.
