"We know how valuable this is for the Cancer Society and how much people had been looking forward to it so it's back on the calendar," James said.
The rally is a "scatter run" which means vehicles will head in several different directions rather than in a procession.
"The rally works on a points system and more points can be earned for solving clues that are further from the starting point so drivers set their own course."
Vehicles must assemble in the Whanganui War Memorial Centre carpark at 12.45pm and they will have two hours to complete the rally.
"All vehicles are eligible to enter," James said.
"Cars, vans, utes, motorcycles, electric bikes, anything road legal.
"There is no need to be a member of the Vintage Car Club or any other club."
Whanganui hosted its first Daffodil Rally in 2016 and has raised around $2000 each year for the local Cancer Society.
"The entry fee is $10 per vehicle but people will often make donations over and above that which all goes to the society," James said.
"It is great to be able to support the Cancer Society while providing an opportunity to have some fun."
