The identity of World Cup venues for 2015 is still several weeks away.
The tournament will be co-hosted by New Zealand and Australia in February-March 2015, and there had been hopes of confirming where the 49 matches will be played this month.
However Therese Walsh, head of New Zealand operations for the Cricket World Cup, said details might not be released for up to two months yet.
"The logistics and practicalities of organising this across two countries are quite significant and it is taking longer than we expected to get it all finalised," Walsh, a board member of New Zealand Cricket, said yesterday.
"There's no problems, it's just a question of working through it all and getting appropriate sign-off from the International Cricket Council."
