"At the end of the day Cricket World Cup will have to carry on. It is an unusual circumstance."
With just 68 days before the tournament begins in Christchurch, Walsh said ticket sales continued to be strong, with the opening game between New Zealand and Sri Lanka and that between New Zealand and Scotland already sold out.
New Zealand vs Australia and West Indies vs Ireland were also getting close to selling out.
"The quarter final and semi final are also both selling very well and there's no doubt in my mind that those will sell out but there are still tickets available."
The highest number of international ticket sales were in Australia followed by the United Kingdom the United States and India.
Some games which would no doubt be exciting spectacles, such as the clash between Sri Lanka and Wellington, still had plenty of seats available and Walsh encouraged Kiwis to get in quick.
Thousands of banners, posters and flags were currently being prepared to be put up around the country as the tournament drew close.
"I can feel the buzz and the momentum building but it's kind of also like you've got a thousand jigsaw pieces to pull together," she said.
