The seller said the "historic" box was an unwanted Christmas gift from their brother "who had contact with the Eagle Boys eagle apparently".
"Unfortunately did not meet my requirements as tried to fit a pizza inside as shown but did not fit, I tried other items but didn't seem to fit my needs as shown in photos."
The pizza box came with a photo of the eagle himself, who the seller speculates "may still be alive in Christchurch".
The Eagle Boys brand was acquired by Pizza Hut in 2016 and shut down in 2017.
A recent Trade Me survey of nearly 2000 Kiwis found 61 per cent said they would have no problem if they found out someone had on-sold their unwanted gift.
Half of those surveyed said they had received at least one dud gift on Christmas Day.
In 2018, there were 20,000 unwanted presents listed and 100,000 searches registered on Boxing Day as opportunistic sellers and bargain hunters jumped onsite.
Trade Me spokesman Logan Mudge said anyone hoping to list an unwanted item on Trade Me should list it in the dedicated section for unwanted gifts.
"If you're keen to avoid hurting any feelings, it's probably best to avoid items that are personalised or easily identifiable, especially if whoever gave it to you is a bargain-hunter."
