The New Zealand Herald is reporting that the Lundy Three Hundy car rally will go ahead this weekend, despite fears of protests.
Organiser Nic Miller said 12 teams had so far signed up for the rally, but more could turn up on the day.
The race is a 300km round-trip dash from Palmerston North to Petone, re-enacting the route Mark Lundy allegedly took in 2000 to murder his wife and daughter.
Miller was expecting protestors to turn up for the start of the rally, which he said was never intended to be offensive.
Lundy's trial is due to take place in the Wellington High court in June.
Police have a contingency plan in place for the rally, which is due to start about midday on Saturday at Karamea Crescent in Palmerston North, and will intervene to prevent breaches of the peace or criminal offences from occuring.
In 2009, Victoria University's student magazine Salient organised a similar event, the Lundy 500, to highlight "wider problems in this country's justice system". But widespread criticism forced then-editor Jackson Wood to cancel the event and apologise.
