Napier City Council has asked the Local Government Commission to put its amalgamation process "on hold" while it addresses what the council claims are "serious errors and misleading information" circulated by the commission late last week.
But the commission is standing by the information it has published, a spokesperson saying it will respond to the council's concerns "in due course".
Wairoa and Central Hawke's Bay district councils have joined Napier City in expressing concern about the information, which is also summarised in a pamphlet being distributed to homes across Hawke's Bay this week.
The pamphlet says while the Hastings and CHB councils have higher levels of debt than Napier and Wairoa, their infrastructure "is in relatively better condition".
This claim, based on information taken from a 133-page consultants' report prepared for the commission, and a five-page in-house analysis, has been strongly disputed by Napier City Council (NCC).
