An Auckland Transport spokesman says some bus services were impacted outside the Commercial Bay shopping precinct.
"There's not a lot of traffic there at the moment, I think it's a bus only lane so a couple of bus services are stopping at an earlier stop," he said.
Auckland Transport says the 95 and 97 buses will be starting and finishing at stop 7036 on Fanshawe St near Victoria Park.
Bus riders should use NX1 services from downtown to connect to the 95 & 97 services at stop 7036.
