Sir Richard Hadlee spent a day at MainPower Oval in Rangiora working with Australian paceman Billy Stanlake.
The imposing 25-year-old, who is 2.04m and bowls at speeds of up to 150km/h, reached out to Sir Richard through a mutual friend - and the 431 test wicket-taker was more than willing to help.
“He’s quite an intimidating sight actually," said Sir Richard.
"I was pleased to work with him. I just put him through his paces and made a few minor technical adjustments, and he responded well to that."
"He communicated well and asked a lot of questions, so I got to know him and was interested in his psychology and approach to the game," said Sir Richard.
"I found it to be a great experience for myself because, in many ways, I'm out of date. I mean I've been retired 30 years and I don't do this sort of thing anymore.
"I was pleased to do it and it challenged me as well. One of (Stanlake's) comments was: 'I've never had it explained to me in that way'."
Stanlake is currently playing for Queensland in Australia's four-day state competition. He took 2/59 and 1/33 in their most recent match against Victoria.
Sir Richard said the pair have a great rapport and he will be following Stanlake’s career with a keen eye.
"He's got a lot of ability and wants to improve his game," Sir Richard said.
"He wants to play test cricket, but he seems to be pigeon-holed to one-day games and T20 games at the moment."
