Beware the new road layout just north of Ōtaki:
SH1 NORTH OF ŌTAKI – NEW ROAD LAYOUT
Southbound has been switched onto the new layout. Please take extra care & adhere to the temporary speed limits. Northbound will not be switched until mid-Sep, at which point the PP2Ō team will focus on the tie-in works at the northern end.
