Ross Taylor smashed 122 in Napier before he pulled up lame with a calf strain and BJ Watling scored an unbeaten 102.
The other century was an innings of pure class when Kane Williamson saved New Zealand's bacon against South Africa at the Basin Reserve in March as he battled to 102 not out as the Black Caps earned a fighting draw.
The ingredients appear to be there, the best players in the country are being picked and the starts are being made - Martin Guptill has passed 50 13 times in 24 tests but has turned only two of those half centuries into hundreds - the batsmen just need to kick on.
Brendon McCullum hasn't scored a test century in his past 23 innings since late 2010 but has racked up six 50s.
You can trot out every statistic you like on the subject but the cold reality is that to win test matches you need players in your top six to regularly score centuries.
In New Zealand's three-test series against South Africa, which they lost 1-0, the Proteas had five individual scores of three figures or more.
When the West Indies drilled New Zealand by nine wickets in the first test on the tour of the Caribbean a week ago, Windies' openers Chris Gayle and Kieran Powell both notched decent hundreds in the home side's first innings.
Aside from the obvious that it provides runs on the board, it gives your bowlers confidence they have a total they can defend and it galvanises a side to see one of your team-mates raise their bat on completion of a century.
Meanwhile, the West Indies closed day three of the second test today (Sun, NZT) on 135-4 in pursuit of 206 for victory.
Earlier in the day, New Zealand began their second innings on 59-2 but a combination of poor application at the crease and questionable shot selection meant the Kiwis were shot out for 154.
Only Guptill (42) and Dean Brownlie (35) managed to produce a score of note and Tim Southee said the side had let themselves down with the bat.
"Some of the shot selection wasn't great but the West Indies bowled well this morning and they had to get themselves back into the game," Southee said.
