While Tipple said "there is no way of knowing" if the shotgun that was sold online to the 28-year-old Australian-born suspect Brenton Tarrant was used in the terror attack, he adamantly denied selling the suspect any semi-automatic weapons. The main shooting happened at Al Noor Mosque in a suburb west of the city center, where 42 people were killed.
"We are very fortunate to be here in New Zealand with people ... who understand our culture and our religion", he said.
Tarrant, from Grafton in NSW, appeared in court on Saturday charged with one count of murder. Tarrant was remanded without a plea and is due back in court on April 5 where police said he was likely to face more charges.
Separately, New Zealand's prime minister Jacinda Ardern said gun law reforms would be announced within 10 days and an inquiry conducted into intelligence and security services who failed to detect the risk from the attacker or his plans.
Since returning to Wellington, Ardern's focus has been on changing the country's gun laws to prevent another similar attack.
Prime Minister Jacinda Ardern on Monday confirmed New Zealand intelligence departments would be called in to probe whether something had been missed - based on Tarrant's travel overseas, gun collection and social media presence.

The Australian has been charged with murder over the worst modern-day massacre in New Zealand in which 50 people were killed at two mosques in Christchurch on Friday.
Iranian-American journalist and commentator Negar Mortazavi praised Ardern for wearing a headscarf, which she said was "a sign of respect" to the grieving Muslim community.
New Zealand Police earlier said that the first body belonging to a victim of Friday's massacre had been released to their family.
"Gun City did not sell him an MSSA, only A-category firearms".
A teenager, whose name can not be published, appeared in court on March 18 charged with distributing that footage.
A New Zealand e-commerce site has already stopped selling semi-automatic guns online.
In the meantime, he says, New Zealand's brands do have the power to choose where they would like to put their money.
"You can get an AR-15 from anywhere really, and while the [30-round magazine] is not allowed legally, they will fit and they will work", said Pete Breidahl, a gun owner and former competition shooter who recently gave up his firearms license.
The victims' names were not made public but a preliminary list has been shared with families, police said Sunday. He said there would be no burials on Monday.
