Martin was named in the White Ferns squad for the World Cup in England next month alongside provincial team-mates Suzie Bates and Leigh Kasperek.
It will be Martin's second one-day World Cup. It is the pinnacle of the women's game and Martin is thrilled to be involved again.
But the right-hander has had to reinvent herself at international level. She made her one-day debut against India in December 2003.
The 32-year-old played three games during that series and then had to wait more than
four years for another opportunity.
The Sparks stalwart was a regular in the White Ferns from 2008 but lost her place at the end of 2012.
She was recalled in February last year and has grasped her opportunity in a new role as a specialist batsman.
''I think with my experience now I'm playing with less fear, whereas in the years gone by I've always felt I was playing for my position,'' Martin
said.
''I've been more consistent and that has allowed me to play with more freedom. I've had the backing of the selectors over the last couple of years which has helped.''
She will continue to provide cover with the gloves but her role is to bat around a powerful top six which includes Bates, Any Satterthwaite and Sophie Devine.
''We've got a balanced team, but obviously our top six is very experienced, and I think that is going to be our strength over there.''
Martin rates the Whites Ferns attack as well. She believes opening bowler Lea Tahuhu and fellow strike bowler Holly Huddleston have enough pace to present problems for top batsmen, while 16-year-old legspinner Amelia Kerr is a rising star and another attacking option the White Ferns can lean on to create opportunities.
''I think it is quite a balanced squad and I know it has been hugely competitive to get into the squad.''
The format for the World Cup is beautifully simple. There are eight teams. Everyone plays each other once and the top four teams move on to the semifinals.
The White Ferns open their campaign against Sri Lanka in Bristol on June 24. The harder games come later in the tournament, when the White Ferns playing the defending champion Australia on July 3, and the host England on July 12.
''It is probably the most competitive World Cup with a lot of the teams in form, so it is a good opportunity to test ourselves against every team,'' Martin said.
''Our challenge will be to make sure we consistently perform well.''
Martin was in terrific form for Otago last summer. She was the leading scorer in the domestic one-day competition with 436 runs at an average of 54.50 and played a key role in helping the team win the twenty20 title.
And since her recall, she has averaged 53 for the Whites Ferns in 18 one-dayers. It is a huge improvement on her overall ODI record of 1141 runs at 25.93.
Her career ODI average of 25.93 is modest but she is a tenacious and experienced player, at the top of her game.
The opposition would be well advised to come up with a decent bowling plan because Martin is not the type of player who throws her wicket away. She shapes as a steadying influence on an aggressive batting line-up.
