WELLINGTON, New Zealand — The ripples from the firing of Matt Lauer as the co-host of the “Today” morning news show have hit the world of New Zealand property, where officials are already scrutinizing the role of foreign buyers in an increasingly expensive market.

A New Zealand government agency said on Thursday that it was in discussions with Mr. Lauer’s representative over his purchase of a 16,000-acre farm there. Foreigners must pass a good-character test to be allowed to buy New Zealand land, and while Mr. Lauer’s purchase was approved earlier this year, the country’s Overseas Investment Office is revisiting his case in light of his firing.

Officials from that agency “are seeking further information,” said Lisa Barrett, a spokeswoman for the agency. The agency can require buyers to dispose of the property if it believes the rules have been violated.

NBC on Wednesday said it fired Mr. Lauer from “Today” following an allegation of sexual harassment, making him the latest major media figure to fall from grace amid a broad examination in the United States of inappropriate sexual behavior in the worlds of media and entertainment. Mr. Lauer, a well-known face on morning television in the United States, had been a co-host at “Today” for two decades.
