McCullum took the first step in avenging a gap on his 13-year cricketing CV by making a World Cup half-century against a test-playing nation. His strike rate of 133 also eased the tension for the five World Cup debutants in his playing XI - Corey Anderson (75 from 46), Grant Elliott (29 from 34), Luke Ronchi (29 off 19), Trent Boult (two for 64) and Adam Milne (two for 56) all made significant contributions as a result.
Before McCullum righted his record yesterday, he had endured a batting blip at World Cups against top-eight teams.
His 2003-2011 record of 414 runs at 31.84 in 18 innings was deceptive. He had scored 308 against nations ranked outside the top eight. The other 106 came at just 10.60, with a best of 36 not out against the West Indies in 2003. Now he's got a clear position and purpose, especially with the likes of Kane Williamson and Ross Taylor as world-class safety nets at Nos3 and 4.
The 111-run opening stand in 15.5 overs from McCullum and Martin Guptill also countered the alarming statistic that, among test-playing nations before the Sri Lanka ODI series, New Zealand had the worst average ODI opening partnership of 22.35 in the previous two years.
