Masu opened upon Mr Watt's return from offshore. He spent eight years with the Roka group, a family of robatayaki-style (where food is barbecued on skewers) restaurants in London, Hong Kong, Macau and Arizona.
The establishment beat out runners up The Engine Room in Northcote Point and Ponsonby fine-dining restaurant Sidart, with last year's supreme winner The French Cafe taking the Best Service category.
Michael Dearth was named Restaurateur of the Year for his efforts in establishing The Grove and Baduzzi, which have both earned five spoons - top marks - in Metro's restaurant rating scale.
Other newcomers, Tom Hishon and Josh Helm of Ponsonby's Orphans Kitchen, were named Best New Talent and Best Renewal went to Mediterranean game-focused bistro Cazador on Dominion Rd.
Cloony was lauded for its degustation menu while Ima and Titirangi's The Refreshment Room were jointly praised for value for money.
Best Drinks List was won by Cocoro, Ponsonby Road Bistro took Best Mid-Size Drinks List and Best Short Drinks List went to Eight.Two.
Waiheke's The Shed at Te Motu Vineyard takes home Best Rural Restaurant.
A team of nine judges including restaurateurs and food writers decided this year's awards, but public votes saw Gatlin Avery of Depot named Restaurant Personality of the Year.
The 2014 winners have been chosen from 50 finalists and will feature in the May issue of Metro.
