Tauranga Mayor Stuart Crosby fears the city could end up with "collateral damage" from a government-ordered inquiry to improve how councils regulate land use, planning and development.
The inquiry by the Productivity Commission expands on its housing affordability report which identified constraints on land supply as a major driver of housing affordability problems.
Commission chairman Murray Sherwin said the new inquiry would delve deeper into how councils made decisions on opening up land for development.
It would also look at how councils increased the capacity for housing in built-up areas through subdivision and intensive development rules.
Mr Crosby said the inquiry was driven by Auckland's housing crisis and could result in collateral damage for Tauranga.
