The NZ Transport Agency is reintroducing roundabout metering on SH29A Barkes Corner roundabout next week. Traffic lights will reactivate using red or amber lights instead of green. A previous attempt to manage the intersection with green lights resulted in car crashes and confusion. The lights will be trialled for 12-18 months. Roundabout metering will also be installed on SH2 Takitimu Dr and Elizabeth St roundabout, with traffic lights on the SH2 northbound approach to the roundabout. These will be operational in early 2019.
