The data was based on the annual survey of city residents, which included a question on how people travelled to work.
It covered private motor vehicles, walking, jogging, cycling or catching the bus.
Mr Grainger's question was prompted by the failure to meet the end-of-year target to increase the proportion of people using alternatives to private vehicles. The goal for more people to feel safe cycling, walking or driving around the city also failed to reach target, as measured by the same survey.
The good news was the participation by school children in walking and cycling programmes: the numbers increased to 4500 per day in the past three months.
Congestion on city roads also received a tick, based on a March report which showed there had been no increase in all-day traffic congestion on Tauranga's key arterial roads. It measured the minutes of delay per kilometre of travel, with delays calculated on actual travel time less what the time would be at the speed limit.
The old chestnut of people feeling that their complaints about potholes and footpaths were being ignored would be addressed by performance measures. Data measuring the council's response time was being developed.
There was both good and bad news around crashes on the non-highway roads owned by council. Fatal and serious crashes were trending down, but overall injury crashes were going up.
"Of particular concern is an increase in the number and severity of crashes involving vulnerable road users," Mr Parkes said.
He also said council was in "a good space" since it signed a travel plan with Trustpower. The plan dealt with the influx of more than 400 workers into the CBD once Trustpower opened its new head office in Durham St next year.
Councillor Rick Curach was concerned about a future shortage of car parks caused by the demands of Trustpower. Mr Parkes said there could be an undersupply of parking during the six months that parts of the Elizabeth St car park building were closed from January for the construction of another storey, adding 110 parks.
