Wheedle boss Carl Rees pulled the plug on the auctions and cancelled Luftwaffe's account minutes after the Herald on Sunday got in touch.
"We don't allow the Nazi insignia," Rees said.
But he added there was "a lot of hype" over Nazi items as "the Brits killed just as many".
"We've got World War II searchlights here. They probably helped shoot down planes."
He said Wheedle relied on members reporting problems and staff checked for people breaking the rules, but it was hard to pick up everything.
No bids had been placed before the Nazi replicas were removed from the site on Thursday, nor had anybody emailed about the auctions.
New Zealand Jewish Council president Stephen Goodman said the fact the items for sale were replicas made no difference.
"It's really the principle of profiting out of other people's suffering that upsets us the most."
Other items for sale on Wheedle but banned on Trade Me are e-cigarettes and courier tickets.
