Former South African wicketkeeper Richardson also praised the work of more than 2000 volunteers during the cup for their "special contribution" to the cup's success.
New Zealand's World Cup boss Therese Walsh is delighted at the way the event captured the nation.
"The ICC just given us huge gold star," she said.
"Operationally we haven't had a major, or significant, glitch, which you're always at risk of when running something this big on a global stage."
Walsh said in terms of crowd attendances, New Zealand had drawn about 325,000 spectators, up towards 80 per cent capacity across all 23 games.
Walsh said given the ticketing and attendance numbers "we are happy that we have certainly protected, but probably enhanced, New Zealand's major events reputation.
"The Rugby World Cup [in 2011] was one thing, but we are not a one trick pony and we can keep knocking them out of the park."
Some staff finish their contracts at the end of this month, but others have another couple of months work to tidy up the operation, which will include final accounting, shareholder reporting and looking at the economic impact for New Zealand.
Around 40,000-50,000 visitors are understood to have come to New Zealand specifically for the cup.
The Wellington weekend, for example, when New Zealand played England is thought to have had a $10 million direct economic impact.
