Mr Dalton said he would not complain to police.
Controversy about signs has featured during the elections. Hastings mayoral candidate Wayne Bradshaw was told by the Hastings District Council one of his election signs was too large and did not meet specifications. A social blogger complained about a sign by Regional council candidate Ewan McGregor over his claim that he "gets things done".
Another sign appeared next to one of Cr McGregor's in Hastings, asking what had he done for the region during the drought.
Cr McGregor said he was disappointed the sign, erected on a Hawke's Bay expressway roundabout, targeted himself and Councillor Kevin Rose.
The sign suggested the two councillors should not be re-elected as people begin filling out their voting forms over the next couple of weeks.
Cr McGregor responded by putting up a new sign, referring people to his website which had details of his work during the dry summer.
The Hawke's Bay District Health Board's pro-fluoride referendum sign was pulled up by the Hastings council for not adhering to rules on advertising signs.
