"I had one year with Robbie. He was a total legend and whatever he said, I went and did. I'm not sure I could pass on too much. It is crazy to think he is now coach [of Australia]," says Maitland.
He has enjoyed a meteoric rise in the world of international rugby, arriving from New Zealand in October to start a new career with the Glasgow Warriors in Scotland, the land of his grandparents. Quickly elevated to the Scotland team, the 24-year-old scored a try on his international debut in the Calcutta Cup match against England at Twickenham in February.
He earned a call-up to Gatland's 37-man Lions squad which opens its tour in Hong Kong against the Barbarians on Saturday before heading to Australia.
"I thought I had a 50-50 chance of making the squad," says Maitland, who helped steer Glasgow Warriors to third in the RaboDirect PRO12 before they suffered a narrow semi-final defeat to Irish province Leinster earlier this month.
"I'm honoured to make it," he says. "I know the hard work begins now. I think you've got to be confident [of making the test team]. We have a few games before the first test [in Brisbane on June 22] and I hope to be picked on form. All the wingers are class players [Welsh duo George North and Alex Cuthbert, and Ireland's Tommy Bowe] but I hope to make it."
Born in Tokoroa, Maitland says the importance of his 'Scottishness' was emphasised by his Glasgow-born grandparents, Stan and June, from a young age. June, now in her 70s, still texts him after every game and is fiercely proud of her grandson being called up to the Lions.
The former Crusaders winger, though, is determined to stamp his mark on the class of 2013 and make the most of his experience in the Lions' den.
"The big thing about a Lions tour is it lasts eight weeks and no-one really knows each other but, by the end, you make some great friends. It will be great to play alongside boys like Tommy Bowe and Brian O'Driscoll - he is a total legend."
