So is that of Black Caps coach John Wright.
"Wrighty really has a good understanding of the players now and the guys really enjoy being around him so I think the combination of the two Johns will be a real asset, not just now but for years to come," the Northern Districts Knights' world-class spinner said in Napier of Wright, who took India to euphoric heights in the international arena last decade.
Vettori on Tuesday made a brief stop at the college for a coaching session after the girls-only school in Havelock North won a Spec Savers-sponsored national competition for his services.
Savouring his time away from the hot seat of captaincy, the 33-year-old left-arm spinner is enjoying watching the Caps thrive while he contributes as a senior player.
"I did my time - some really good times and some really tough times - so it's good to sit back to see Ross [Taylor] do so well and now Brendon [McCullum] do so well," he said, after wicketkeeper McCullum took over the leadership last month when Taylor injured his calf muscle after making a century against Zimbabwe in Napier.
Other seniors, such as Kyle Mills and Jacob Oram, were also an asset to Taylor and McCullum.
He felt Zimbabwe was adequate preparation, considering the Black Caps' victory in the first Twenty/20 match against South Africa in Wellington last Friday showed how much the Black Caps had grown in confidence.
"[Proteas opening batsman] Richard Levi in the last game was exceptional so I think they'll counter that in the next game [last night]," Vettori said, adding the two sides appeared to be pretty evenly matched in the limited overs but the test match would separate the men from the boys.
Vettori is an advocate of playing the four-day Plunket Shield cricket at this time of the year. "In the past, it's always been changing from T20s to one-dayers and test matches so sometimes the batsmen get a real good look at you before the important test matches come along.
"This time, we have been able to prepare away a little bit but still play competitive cricket so I've been impressed with New Zealand's first-class cricket."
Having four spinners representing New Zealand in a game also won plaudits.
"It's the luxury of Rob Nicol and Kane Williamson batting in the top four," he said, adding Yuvraj Singh, Andrew Symonds, Virender Sehwag and Suresh Raina were a testimony to that logic because of their ability to roll their arm, too.
"Kane and Rob have done a great job so far.
"Nathan [McCullum] has continued to impress in the limited-overs format and now Tarun [Nethula] and Roneel Hira are getting a chance and they have done a good job in the short time they have been involved."
Having played with BJ Watling behind the stumps at ND level, Vettori had confidence he would grow as test wicketkeeper.
"Other people may not have been [sure] but he was ready for it. He's done a good job in such limited time.
"It's a pressurised job because if you drop one catch people start talking about it all the time but he's good enough, particularly with the gloves and with the bat, which he showed in the last test match," he said, although he felt Central Districts Stags wicketkeeper Kruger van Wyk was equally adept.
"It's reassuring there are some guys in the background who are pushing for a spot and that's what you want from a competitive environment ... so people generally don't get lazy and work hard all the time."
Lapping up the intricacies test matches offer, Vettori felt he still had at least two years to contribute at international level.
"If we keep improving as a test team, as we've done for awhile with this group of young fast bowlers and the development of good batsmen, we'll hopefully make it a winning environment."
Most test matches were about putting big first-innings totals, something New Zealand had done well recently.
Employing four seamers and a spinner - a formula that worked in the historic victory against Australia before Christmas - was the blueprint to incremental success.
With Jesse Ryder's "exceptional" talent, Vettori had no doubt the ex-Hawke's Bay batsmen would lift his fitness to feature in Wright's equation for the three-test series against South Africa early next month after the conclusion of the ODI series.
The three ODIs begin with a day-nighter on Saturday in Wellington before coming to McLean Park, Napier, on Wednesday next week and finishing in Auckland on March 3. The test starts on March 7 in Dunedin.
