This right turning lane appears to be marked as the main (straight ahead) continuation of the Lower Plenty road for navigation, which is incorrect. I was using OsmAnd in car navigation mode, the map showed it wanted me to travel SW down Lower Plenty then go North on Waiora Road; however no direction was given for this turn, the program treated it as if I was just following the road around. This would have been confusing for anyone unfamiliar with this intersection.

Description of physical intersection: the two lanes to navigate from Lower Plenty Rd (SW) to Upper Heidelberg Rd (S) is marked as straight ahead, while there is one right-turn slip lane to go from Lower Plenty (SW) to Waiora Rd (N).
