We will be in Wellington the nights of April 7 and 8, 2018, having taken the ferry from Picton after our driving tour of the South Island and beginning a couple of weeks on the North Island. I discovered last night that a large concert event called Jim Beam Homegrown is scheduled to take place the afternoon and evening of April 7 in the harbor area. I'm curious what this means for our ability to visit downtown sights Saturday afternoon and Sunday, especially Te Papa (which is surrounded by the event stages). Would we be better off staying outside downtown and taking public transportation to the CBD? Or staying downtown so we can walk to whatever we want to see? Will public buses be packed with event-goers? Assuming the event takes place on Saturday the 7th, do the crowds dissipate by Sunday?
I appreciate any input based on experience with the event from previous years.
