*McCullum is the first New Zealand batsman to score a triple-century (302) in Tests. He went past Martin Crowe's 299 against Sri Lanka at the same venue 20 years ago.
*Only 24 cricketers have broken the 300 barrier, four of them twice -- including West Indian Brian Lara, who holds the world record for the highest Test innings of 400.
*After his 224 in the first-Test win, McCullum became the third man after Australia's Donald Bradman, and England's Wally Hammond in the 1930s, to score double and triple tons in consecutive Tests.
*McCullum became only the second batsman in Test history to make a triple-century in the second innings after Pakistan's Hanif Mohammad's 337 against West Indies at Barbados in 1957-58.
*McCullum is only the eighth captain to hit a triple hundred in Tests. The last one to do it was Michael Clarke, who scored an unbeaten 329 against India at the SCG in 2012.
*McCullum's innings lasted 775 minutes, the eighth-longest innings in Test history. Hanif Mohammad tops the list for batting an estimated 970 minutes in the Barbados Test.
*New Zealand's score of 680 for 8 is the highest by any team in the second innings of a Test. They beat their own record of 671 against Sri Lanka at the same venue in 1990-91.
*On way to his dream triple, McCullum took part in a world-record, 352-run sixth-wicket partnership with BJ Watling (124).
