Forsythe said the organisation typically received about 750 from US nationals interested in working, studying or investing in New Zealand.
"In the past week, 13,401 registrations have been received from American citizens - more than 17 times the number of a typical week's registrations."
Forsythe said it was important to note that registrations of interest were simply that and were different to visa applications.
And it seems even New Zealand's big earthquake has not put people off, with the number of visitors to the sites still high days after the quake struck.
"To put these figures into context, 1288 Americans were approved residence in the year to June, 8876 Americans were approved work visas and 2997 Americans were approved student visas.''
Meanwhile, international news and social media websites have continued to discuss why New Zealand would be the ideal place to move to, post-Trump.
US environmental news site EcoWatch ran an article early this week giving five reasons to consider moving to Aotearoa.
The reasons included the idea that Kiwis respected the land, that politicians here care about climate change - unlike Trump, the article said - and that there was plenty of room for more people.
The article did, however, get the name of the NZ Prime Minister wrong - giving credit to "Prime Minister Sir Geoffrey Palmer's'' comments to a media outlet that climate change was his biggest worry about a Trump presidency.
Canada's immigration website crashed after swarms of Americans began visiting it when a Clinton presidency started to look like a no-go.
