The Kiwis were in typically ferocious form throughout this year's Rugby Championship yet let their invincibility slip in defeat to South Africa last weekend, albeit with the title already wrapped up.
Wales themselves have not won against a Southern Hemisphere side since November 2008 - a 21-18 victory over Australia - but Jones believes beating New Zealand is no impossible dream.
"Yes, it's a daunting ask," Jones told Wales Online.
"But you look at the Rugby Championship and there have been a few wins and losses there you wouldn't have seen last year and you wouldn't expect.
"You've got Argentina beating Australia and South Africa beating New Zealand.
"Is something changing or is it one of those seasons because it's the start of the World Cup year? You don't know."
