The spring meeting is traditionally the WJC's biggest raceday with the Listed H S Dyke Wanganui Guineas, the Listed O'Leary's Fillies race and the first two-year-old event for the season in New Zealand the main attractions.
However, with three black type events programmed for Saturday the Queen's Birthday fixture will now rival the sping meeting for importance. With $270,000 total stakes on offer this weekend's meeting will trump September's when $230,000 will be up for grabs.
WJC operations manager Bret Field said this Saturday's meeting was expected to attract large numbers.
"Our bookings are huge," Field said.
"Normally Ag Challenge hosts big numbers in the Wanganui room as sponsor of the main race on the day, but has opted to rescedule that celebration for another date to help us cater for others. It is the Marist Rugby Club's centenary celebrations over Queen's Birthday and many of those attending have signalled they will also come to the races, while the St John Club have doubled their traditional numbers from 50 to 100 and that's in addition to all our other usual racegoers - it's going to be huge," Field said.
The first of the nine race card starts at 11.42am with the final event timed for 4.17pm.
