Neho would be the only player to break par with a remarkable 71, undoubtedly the round of the tournament given the horrendous southerly ripping through the area.
Another round of 71 in testy conditions on Saturday allowed him to retain the lead, albeit by just one shot, when North Harbour's top junior boy representative Campbell shot a superb 68.
Sunday finally brought calmer conditions for the 50 players that made the cut.
Neho and Campbell shot 70s in the morning's third round to open a sizeable gap between them and the rest of the field heading into round four.
It would, however, be Neho's front nine in the afternoon that would clinch the title. The form would continue early into the back nine as he reached six under par for the round after just 14 holes.
Even a slightly messy finish - of bogey, double bogey, and another bogey - could not thwart his victory stroll and his final round of 70 was good enough for the six-shot win and a four-round total of 282.
Strong final rounds from Brad Hayward of New Plymouth (68) and Ryan Chisnall of Greenacres (69) resulted in them finishing tied for second on 288.
The Muriwai Links was again prepared in fantastic condition for the championship and has been a popular venue of the tournament in recent years.
