Footage showed black smoke billowing from the truck parked next to a rugby field at Rugby Park.
Whakatāne District Council said via social media: “We’re aware of the fire which occurred earlier this morning at Whakatāne Rugby Park.
“We’d like to firstly thank the organisers and MC who did a stellar job of calmly directing participants and supporters of the Bay of Plenty Rugby Youth Development Cup away from the area,” the post said.
“To the Whakatāne Volunteer Fire Brigade crew who responded promptly ensuring the safety of everyone involved - you’re absolute legends.
“We are so grateful there were no injuries and feel privileged to be part of such an awesome hapori/community where we all look out for one another.”
