The ASA said there were no grounds to proceed with either complaint, saying the ad had not breached the code of ethics and was "a light-hearted and cliched montage of New Zealand culture and history".
The authority also cleared a Fisher & Paykel Appliances ad which was accused of grossly exaggerating the length of a dog year.
The television ad, which showed a dog sitting in front of a front-loader washing machine, said patience could not be taught, so the company had developed a way to reduce the wash time to 15 minutes.
"Sadly, that's still about a week in dog minutes," the ad said.
The complainant said 15 minutes was actually equivalent to one hour and 35 minutes in dog years, as calculated using the "generally accepted" ratio of seven dog years to every human year.
The complainant's own calculation was wrong - seven times 15 minutes is actually one hour and 45 minutes.
The ASA, which did not note that discrepancy itself, said there were no grounds to proceed with the complaint.
It said the ad referred to dog minutes, not dog years.
The ASA also said the ad had used comedic hyperbole and was unlikely to mislead or deceive consumers.
