Willacy thanked also the local industry businesses who have given assistance to make the event what it is - such as Hookers who were using their trucks as barricades on the streets.
"We could never afford to do that, we didn't get charged for this."
As a reminder, spectators may bring their own alcohol into the event, however there is no glass allowed and the levels are restricted to a dozen cans of beer or six cans of RTD, with zero tolerance for more by security on the doors.
However, Willacy said in recent years the public have been more understanding of this, as in 2015 the staff only took away half a trailer of rubbish, compared to two trailers worth in previous events.
"People are starting to mello. They understand it's a family event."
In 2015, Willacy accepted the trophy for Best Established Regional Event at the NZ Association of Event Professionals awards, which recognised that Cemetery Circuit pours around $2m into the economy as Whanganui's most economically beneficial annual event.
