Willacy said members of the public could save money by purchasing 'early bird tickets' through Ticketek on-line and then they'll also go in the draw to win a Suzuki Gixxer 150 bike.
British rider Richard Cooper, Ireland's Lee Johnston and Frenchman Morgan Govignon are the main draw card entrants this year, with many race fans sure to already know of their incredible international exploits.
Cooper is the British Superbike Championships (BSB) Superstock Champion for 2019 and his performance as a newcomer at this year's North West 200 was a definite highlight of that iconic event.
He will race in New Zealand for the Sloan Frost Motorsport Team.
Johnston is the 2019 Isle of Man TT winner, which was icing on the cake to his 2019 season, having also won the Scarborough Gold Cup and finished runner-up in the Ulster GP.
Johnstone raced in New Zealand at the Suzuki Series in 2017 and he returns this year riding a BMW1000 under the M1 Motorsport NZ banner.
Govignon will be riding in the Bears Class.
He will also be riding a special one-off Voxan in memory of good friend Fabrice Miguet, who unfortunately died at the Ulster GP.
Meanwhile, fellow French rider Estelle Leblond and Belgium's Frank Claeys will also debut at the series this December.
Leading French sidecar driver Leblond is set to link up with fellow accomplished high-calibre Isle of Man Mountain Course exponent Claeys for racing at Taupo, Manfeild and Whanganui.
Both Leblond and Claeys respectively have impressive Isle of Man TT records, which include securing between them nine top-15 finishes and overall 13 top-20 finishes.
Another French rider, Xavier Denis, will also debut in New Zealand this summer.
Overall sixth within this year's IRRC Supersport series, additional highlights from this season for the amiable Frenchman included his achieving top finishes at Circuit De Chimay and the Southern 100, plus he scored a collection of creditable finishes at TT 2019.
Denis will be riding F2 on a Triumph Dayton 675 and in the F3 class on a Kawasaki 650.
Australian-based rider Steve Marshall first raced in New Zealand during the NZ Marlborough Series 1977 and moved to Australia in 1979.
Teaming up with Australian Murray Stronach, the duo competed in multiple Western Australian and State Championships sidecars events, gaining many titles.
Marshall retired in 1995 but came back again in 2016 with Stronach.
They both came out to New Zealand in 2017 for the Suzuki Series and have returned, bringing two of Steve's sons who will also compete.
Australian brothers Morgan and Dion Marshall will race in New Zealand for the Marshall Brothers Racing Team.
Morgan Marshall started in 2016 and sibling Dion joined him as passenger in 2018, the duo only having to wait till April 2019 for their first win.
They wanted to take the opportunity to race against their father on overseas circuits, which is what brings them to this year's series.
Several notable Trans-Tasman partnerships will also be on track this season.
Australian Sam Watson will join up with Kiwi Jo Mickleson in the sidecars class, alongside another Aussie/Kiwi pairing in Jeremy (Jero) Joyce and Louise Blythe.
However, the international stars won't be having things all their own way, with New Zealand riders also world class competitors.
Suzuki's former national and series champion in the F1 class, Wellington's Sloan Frost, will be determined to win again.
Last year's series outright winner and fellow Suzuki rider Scott Moir, from Taupo, and Suzuki's 2019 national superbike champion Daniel Mettam, from Glen Eden, won't be taking a back seat either.
Wainuiomata's Shane Richardson returns from overseas, where he is currently leading the British Superbike Championships in the superstock class.
He will race a 1000cc Kawasaki in the F1 class in the series.
Wellington's Glen Skachill returns to racing after a number of years away and he will also add spark to the F1 class on his BMW bike, while reigning national 600 Supersport champion Avalon Biddle has delighted organisers with news that she will race the series and make her debut on the public streets of Whanganui on Boxing Day.
Rangiora-based Kiwi international Biddle will race her ZX6R Kawasaki in the F2 (600cc) class.
"I feel this is a reflection of the confidence riders have in the increased safety measures that we have put in place over the past few years.
"These top riders perhaps feel they can now commit to pushing it even harder on the street circuit," said Willacy.
The series also offers races for Formula Three, Classics (pre-89), sports bikes, super motard bikes and sidecars, so there's no shortage of on-track action.
The always-popular Gixxer Cup class, reserved for riders on identical 150cc Suzuki GSX150F model bikes, returns to the programme again this year with the rider age-limit restriction lifted.
This means individuals such as Frost, Moir and Mettam are expected also to line up and give talented youngsters such as Jesse Stroud (Hamilton) and Caleb Gilmore (Whanganui) something to really think about.
