Concert promoter Brent Eccles says tickets for Six60's McLean Park gig are tracking "very well" and he predicts a turnout of about 20,000.
"I think the show is going to be great at that venue, it should be a popular one," Eccles said.
Napier City Council events manager Kevin Murphy said the gig on April 2 will be the first full-sized concert ever at Mclean Park and its biggest since 1984.
"In 1984 we've had Split Enz, which was 6000 people, and in 2013 Stan Walker did an Easter concert and there were about 1200," Murphy said.
Preparations are still in the early stages with travel restrictions on some of the promoter's Auckland-based staff.
