A spokesperson for the government confirmed to RNZ Pacific the small nation of three atolls announced the first-ever case on Sunday.
Up until now Tokelau, which is a dependency of New Zealand, was the last remaining country along with Turkmenistan to not have experienced community cases.
The case is located on Nukunonu, the largest atoll in Tokelau and does not know how they caught the virus.
Work was under way to establish how the virus entered the community.
In January, Tokelau experienced its first cases of the virus at the border.
All five people who tested positive then tested negative and were able to join the community and attend a wedding.
