"Our consultation with rural communities is very robust," Mr Martin said.
"We moved it from October to May, but unfortunately staffing changes in our organisation didn't highlight the need for the six-month lead-in.
"We deal with 52 councils across New Zealand and have now replicated the TDC (Tararua District Council) requirements as standard across all councils."
One of the special conditions for all motorsport organisers is that they must avoid August, September and October for events in Tararua because they are peak calving and lambing periods.
There was one objection from Barry O'Shea to the rally, on the grounds no third-party insurance was provided by the organisers and individual drivers must cover the cost of any damage they may cause.
However, Victoria Main told councillors this wasn't the case. There was motorsport public-liability insurance to the value of $10,000,000.
"We've letter-dropped and received no objections or negative responses," she said.
But councillor Ernie Christison said a lot of the residents on Top Grass Rd didn't want the rally on their road.
"It's (the rally) a nuisance for farmers," he said, before confirming residents hadn't actually put their objections to the organisers or council.
The rally organisers also agreed to withdraw Whenuahou Rd from the itinerary as it was a no-go road under the council's special conditions for rally events, but urged the council not to send contractors to repair potholes on Waione and Horoeka roads.
"Loose chip means more damage to roading and we do a road check, giving competitors notes on dangers," Mr Martin said.
Councillor Carole Isaacson told the meeting the Targa Rally brought visitors to the area.
"I'm fully supportive and have no problem with it," she said.
Councillors agreed to allow the event to go ahead.
Mr Martin confirmed 12 community groups would be involved as the rally passed through the Tararua, with their lunch stop at the Dannevirke A&P Showgrounds.
* The Targa Rally will be in Tararua on Sunday, May 21.
