The information came to light following a lengthy legal challenge to the Prime Minister's Office and Foreign Office from lawyer Shahar Ben-Meir, who petitioned the Jerusalem District Court under the Freedom of Information Law, the Haaretz newspaper reported.
Netanyahu and his wife visited New York between September 29 and October 4 2015, and the bills were paid by the Israeli consulate and the Israeli mission to the UN.
According to a spreadsheet of costs compiled by the consulate on January 17, the lion's share of expense went on the flight to New York, which cost $1.5 million.
In addition, meals for Netanyahu and his wife Sara cost $1,860, and their laundry cost $210.
According to Haaretz the separate expenses of Netanyahu's wife have not been released; earlier this year Israeli police recently recommended that public prosecutors indict Sara Netanyahu for allegedly wasting public funds in the couple's residence.
One of the most surprising expenses listed is almost $20,000 for the removal of furnishings from their hotel rooms, presumably to accommodate guests. This included $3,500 for removal, and $16,000 for storage of the furniture.
