The Hawke's Bay Trails saw a 15 per cent increase in traffic during lockdown, despite a quarter of them being closed and no tourists.
But a recent big jump in Clifton made Cycle Network co-ordinator Vicki Butterworth take notice.
It was highly unusual, with 20,000 pedestrians recorded at the remote spot of Clifton.
It prompted her to take action.
The information was thanks to expensive sensors hidden throughout the network which can count users and differentiate between cyclists and pedestrians.
