His unforgettable knock surpassed Martin Crowe's 299 against Sri Lanka in the 1990-91 season and took McCullum 774 minutes to become the longest test innings played by a New Zealander, going past Glenn Turner's 704-minute epic against West Indies in 1971-72.
McCullum faced 559 deliveries in his marathon innings, the most deliveries faced by any international batsman in tests in New Zealand, and he became just the second batsman to score a triple century in the second innings after Pakistan's Hanif Mohammad back in 1957-58. Only Walter Hammond and Don Bradman have scored a double century and triple century back-to-back in a series.
But perhaps the record the ultimate team man McCullum will cherish the most is the world record sixth-wicket partnership of 352 he set with BJ Watling on Monday.
What McCullum has achieved is not just an unforgettable milestone for New Zealand cricket but a special moment in our collective sporting consciousness.
Take a bow Brendon McCullum - you have made us all proud.
