Rugby fans have talked for years about potential responses to the famous Haka but this, not surprisingly, was never suggested.
Children from Norton Junior School produced a quite stunning performance of the Maori war dance - in front of New Zealand rugby players themselves.
Around 50 schoolchildren gave the visiting New Zealand team a welcome to remember with their own version of the Haka, and then had to stand back and observe the response.
The Kiwi tourists proceeded to perform their own Haka in front of the children from Doncaster, and it's hard to know which was the more impressive.
The Mayor of Doncaster, Ros Jones, said: "It is a major coup to be welcoming the world champions New Zealand - and the Cook Islands to Doncaster.
"The town has a proud history in rugby league and I am delighted that schoolchildren got to perform the Haka. They put on a tremendous display, it was really quite fearsome!
"I am sure that it will remain in their memories for some time and we thank the Kiwis and the Doncaster Rugby League for helping make this visit happen - and of course the schools for taking part."
The New Zealand players are scheduled to visit around 14 schools as part of a tour as they train and prepare for the forthcoming Rugby League World Cup.
