A third of Kiwis said they received unwanted gifts, and many rewrapped and offloaded them on someone else.
Unicef said it could help end the circle of unwanted gifts with its "Say No to Naff" and "Inspired Gift" ideas.
The children's charity's online marketing manager, Richard Boyd, said those who bought the Inspired Gift had the chance to help children and their families in developing countries.
"[It] takes the hassle out of Christmas shopping and means your present definitely won't end up unloved."
Unicef NZ Ambassador Jonah Lomu also lent his support to the "Say No to Naff" campaign, saying it was a chance to change kids' lives in more than 60 countries around the world.
"That's the kind of gift I think all of us would want to receive under the Christmas tree," the ex-All Black said.
