"All I would say is I'd like people to reflect on who the complainants are."
He had been contacted by the Office of the Auditor-General, but said the subject of this contact was private.
A spokesperson for the Office of the Auditor-General said it had recently received "several pieces of correspondence relating to Napier City Council".
"We are currently considering each item and the issues they raise."
Two of these complaints - made by former councillor John Harrison - were reported earlier this week.
The other two complaints laid include one sent last week by Watchdog! chairwoman Jessica Maxwell.
The animal advocate group last year requested the Ministry for Primary Industries investigate Napier's animal welfare centre, alleging there had been abuses of the Animal Welfare Act there.
She requested the OAG investigate the actions of Mr Jack during October of last year, in relation to the resignation of an Animal Control Officer (ACO) before the investigation stated.
It was alleged measures were taken to stop the ACO, Wayne Butcher, from taking part in the investigation. The council denied this at the time.
The MPI investigation stated there were major non-compliance issues found at the pound, but there was no, or insufficient evidence of, breaches of the Animal Welfare Act "in relation to the Napier City Council, the Animal Control Unit Team Leader or Animal Control Officer in the 11 incidents investigated".
The most recent complaint was laid on Thursday, by Napier resident Velma Farquhar, over the council's conduct in relation to infrastructure on Hospital Hill.
In her complaint, Ms Farquhar said the council had not fixed a partially retained roadside on Hospital Terrace, which left properties exposed to water seepage, and damage.
A lack of stormwater systems - which three properties on this road had been paying for - was also causing damage.
"Infrastructure to control water is severely lacking and [the council] won't spend the money to gain some level of control," she wrote.
"We want our weeping and vibrating non-retained roadside fixed, and stormwater access given to three houses who have been paying for it for 80 years and never had it," she wrote.
Mr Jack has said the current asset strategy team intended to review the extent and capacity of the stormwater network across Napier, and that the issue of stormwater discharge appeared to have become an issue only after the property owner modified the way in which stormwater was discharged.
He said council officers had visited the property on several occasions and in their professional opinions, these assertions are not supported by visible physical evidence.
Mr Harrison's two complaints related to public exclusion during the redevelopment of the Napier Conference Centre, and that Mr Dalton had been biased in the process of recruiting a new chief executive.
For his first complaint, Mr Harrison emailed the office that there was no reason for the Napier City Council to have voted "in committee" on the decision to rename the Napier War Memorial Conference Centre and to remove the Eternal Flame and Roll of Honour.
In his second complaint, Mr Harrison said Mr Dalton had shown a clear case of predetermination in ensuring that the applications received for the role of chief executive were effectively ignored and called for councillors to stand by current CEO Wayne Jack, who was understood to have reapplied for the position.
