After India beat New Zealand to secure the title, four officials were part of the presentation ceremony, including Jay Shah, the ICC chair, two from the BCCI, one from New Zealand Cricket but none from the PCB. Other than Shah, the officials present were BCCI president Roger Binny, BCCI secretary Devajit Saikia and NZC director Roger Twose. It is not customary for representatives of nations playing the final to feature in post-tournament ICC ceremonies, unless the final involves the host country.
