Cooper has been frustrated at Woodville over the past few years, the Honda star typically winning the 450cc battles but losing the war.
Cooper dominated the MX1 class races last season – finishing with a 1-1-2 score-card over the weekend – but then the event's namesake feature race was won instead by Hamilton rider Lamont.
In clinching the Invitation Feature Race, Lamont became the 29th different main event winner at Woodville since the inaugural running in 1961.
Lamont will be back to torment Cooper at Woodville this time around too, as will Gibbs, winner of the New Zealand MX1 crown at the nationals last season.
Taupo's Wyatt Chase won the MX2 (250cc) class at Woodville last year, while Mangakino's Maximus Purvis was crowned the crowned 125cc class champion at Woodville in 2018 and these two will this year go head-to-head in the MX2 class.
In addition, the Woodville GP will once again this year also be recognised as an FIM Oceania event.
The spectacular two-day meeting welcomes the enhancement as a true international competition, with the FIM Oceania status attracting huge interest from overseas.
Kiwi internationals such as Mount Maunganui's Rhys Carter, Waitakere's Hamish Harwood, Taupo's Brad Groombridge, Rangiora's Micah McGoldrick, Waitakere's Ethan Martens, Tauranga's Brodie Connolly and Wairoa's Tommy Watts also have good reason to fancy their chances.
Racing over the two days at Woodville caters for minis, juniors, women, veterans and seniors, with the novelty river race on Sunday always a crowd-pleaser.
