Maybe NZ Football didn't get the fax from FIFA but I'm under the impression that FIFA are cancelling all their men's age group World Cups next year (apart from the Olympic u-23's).
Read this in August World Soccer magazine.
Reasons:
- Qualifiers can't be played in most Confederations due to covid-19
- Crowded calendar in 2021 with Olympic Football, Copa America and Euros.
I just checked the FIFA website and all references to men's age group World Cups have been removed except the Olympics.....

Only the Women's u-17 World Cup is still listed.
