The slow left-armer, 33, made a long-awaited Test bow against England in Dunedin in March and went on to play all three matches of the tour in the continued absence of Daniel Vettori. He impressed with figures of four for 43 on debut and followed up with four for 103 in Wellington as the Black Caps defied the odds to draw all three matches.
"It's very exciting, at 33 years old it's just wonderful to be playing Test cricket," he told Press Association Sport ahead of the three-day tour match against Derbyshire which begins on Saturday. "This is the highest moment yet for me."
With Vettori still not considered fit enough for the longer format he could get more chances to take on England at Lord's and Headingley and he admits it is a dream come true to tour with the national side.
He added: "Every game seems to be another high at the moment and I'm just relishing every chance I get.
"Getting the chance to play at somewhere like Lord's and against an England side ranked number two in the world is wonderful. I thought I'd done enough in the last series and thankfully I had."
It would be wrong to think that Martin is simply a contented tourist, though, and he is in no doubt about what the objective is.
"If everyone does their job and plays well I think we can beat anyone in the world," he added. "A draw was nice but we want to do the full job this time. Hopefully we can knock them over this time."
New Zealand have been boosted by the early release from Indian Premier League duty of captain Brendon McCullum and senior batsman Ross Taylor.
Both men had initially planned to link up after the Derbyshire fixture but, after discussions with their respective IPL franchises, McCullum was en route on Friday, with Taylor joining up with the squad on Saturday.
