Public transport usage in Auckland will probably fall short of targets this year and growth on the railway network is stagnating.
Auckland Transport said growth is sluggish for rail, as well as on express bus services using the northern busway, and its target of 74 million journeys may not be reached.
Stripping out a boost from last year's Rugby World Cup, there has been almost no growth in use on the rail network.
Auckland Transport said weekend shutdowns while electric rail equipment is built are hurting patronage and surveys show peak-hour crowding has discouraged commuters.
Chair Lester Levy said a boost patronage is needed before electric trains come into service late next year.
