He said the 'brownies' billboard was as close to the line as the company wanted to push things, despite receiving many calls of support.
"We probably didn't expect it to offend as much as it did. But we sleep easy at night because we know we are not racist guys. It was light-hearted."
Hell holds the record for complaints after 685 people contacted the authority over a 2006 campaign for 'Lust Pizza' which involved sending out condoms in the promotion material.
But Blomfield said the company had a good relationship with the authority, who released details of 2009's 10 most-complained about ads this week in its annual report.
"We have a lot of respect for the ASA and always uphold their decisions." Blomfield described many people who complained about Hell ads as "Nazis".
"For every one complaint we get another 10 calls congratulating us."
The authority received 1339 complaints about 829 ads last year, up from 1246 about 703 ads in 2008.
Executive director Hilary Souter said the watchdog aimed to encourage creativity not stem it.
"Last year was pretty hard for a lot of companies and ads are big investments. Some wouldn't have wanted to risk having the ad ordered off."
She said some language used in advertising was more acceptable to the public than it would have been five or 10 years earlier.
An example was Toyota's infamous "bugger" campaign in 2005.
AUT University marketing professor Roger Marshall said most companies didn't want to offend but some pushed the envelope.
Many companies weren't bothered if they cause minor offence because it could generate free publicity and work well with their market, particularly young people.
