New Zealand Cricket Chief Executive David White Sunday admitted that the board was initially satisfied with security arrangements in Pakistan which is why they sent their team to the country.
New Zealand made headlines around the world when the cricket team called off its ODI and T20 series minutes before the toss for the first ODI between the two sides was scheduled to take place in Rawalpindi.
New Zealand had arrived in Pakistan after 18 years to play a cricket series.
However, White said that "everything changed" on Friday.
"The advice changed, the threat level changed and, as a consequence, we took the only responsible course of action possible," he said.
White said that it was unfortunate that the series was abandoned at the last minute, adding that there was no way that it could be held after the intelligence of a potential attack was received.
"What I can say is that we were advised this was a specific and credible threat against the team," White said.
White some information had been shared with the Pakistan Cricket Board, however, "specific details could not, and will not, be disclosed - privately or publicly", New Zealand Cricket chief executive David White said.
"We had several conversations with New Zealand government officials before making the decision and it was after informing the PCB of our position that we understand a telephone discussion was conducted between the respective prime ministers," he added.
He acknowledged that it was a "terribly difficult time" for Pakistan cricket but reiterated that New Zealand had no other option.
NZ cricketers arrive in Dubai
The New Zealand cricket team arrived in Dubai early Sunday after fleeing Pakistan but officials refused to give details of the security threat that forced them to abruptly cancel their tour.
"The BLACKCAPS have arrived in Dubai after leaving Islamabad on a charter flight last night," New Zealand Cricket said in a statement.
"The contingent of 34 players and support staff are now settling into their Dubai hotel and undergoing their 24-hour period of self-isolation."
