The veteran Otago wicketkeeper-batsman clipped a delivery from Tayla-Leigh Hollis for a boundary to raise her fifth one-day hundred and seal a six-wicket win for the Sparks.
Otago swept Northern Districts in both one-dayers at Lincoln and also won the twenty20 match on Wednesday.
The 32-year-old played a key role in all three victories, scoring back-to-back half centuries in the opening two games before rounding out the series with an undefeated 102.
To add to the occasion, Martin became the first Otago player to play 150 one-day games for Otago on Thursday.
"It has been a pretty good few days," Martin said.
"But I tell you, I’m feeling it now."
The Otago captain was quick to divert attention from her achievement and heap praise on the bowling unit.The Sparks restricted Northern Districts to an under-par total of 224 for nine.
"We bowled really well and it was good to be able to finish the game off and get a not out at the end."
Northern Districts built slowly with opener Natalie Dodd taking her time to get established. Kate Anderson was more aggressive, striking six fours in her knock of 41 from 56 balls.The pair put on 86 before Anderson was undone by Emma Black.
Dodd kept plugging away but lost the fight on 43. She skipped down the wicket and was stumped.
Samantha Curtis (38) and Bernadine Bezuidenhout (31) upped the ante but their demise triggered a rapid decline.
The wickets started to tumble a little too easily and Northern waved goodbye to a much more competitive total.
Leigh Kasperek took control during that period and claimed three for 36, while fast bowler Beth Langston was parsimonious. She took two for 26 from 10 overs.
Otago got off to a stuttering reply. Caitlin Blakely went for eight and Morna Nielsen (14) and Polly Inglis (19) got set but could not go on.
But the key partnership always shaped as the one between Martin and Kasperek.
The pair put on 116 on Thursday and came together yesterday with Otago 57 for three.
Martin was the aggressor this time, while Kasperek was content to accumulate. The partnership grew as well and had reached 132 by the time Nensi Patel bowled Kasperek for 47.
With victory all but assured, the only thing left for Martin to do was get through to her fifth one-day ton before the Sparks reached the target.
Martin stepped to off and flicked the ball through square leg for a boundary to complete her century and win the game.
"It was pleasing to score a hundred but it was more important to be not out and lead the team through."
In the other two games, Canterbury beat Central Districts by 64 runs while Wellington downed Auckland by four wickets.
