Tomorrow night the 30-year-old constable is more likely to be pulling someone's jersey.
The loosehead prop will be making her 100th appearance for University when it plays North Otago in the semifinal of the women's competition at the University Oval.
She will be just the third woman to reach the milestone for the club after Beth Mallard and Chloe Hawken.
It is quite an achievement for the affable "tomboy'' from Masterton and it has been a very interesting journey as well.
Ammundsen started out as a first five-eighth but is now using those silky skills in the front row.
She moved to Dunedin in 2004 and joined the University club in 2006. She had a stint as coach in 2014 but decided she wanted to keep playing.
"I thought I'd give coaching a go but I just missed playing too much, so I put the boots back on,'' she said.
"I decided I was getting too slow and too big for first-five, so I moved to the front row, which is good. It's good fun.''
She was a little nervous packing down for the first time, but changes to the scrum have made that aspect of the game much safer.
Ammundsen has won two titles with the club. The first was during her debut season for the club in 2006 and then again in 2013. And "finger's crossed'' there will be a third in 2016.
University should be too strong for North Otago. The team has had just one loss this season and that was against Pirates, which shapes as the team to beat.
Pirates plays Alhambra-Union in the other semifinal tomorrow night - also at the University Oval - and Ammundsen is picking it will make the final.
Her highlight during the past 10 years at the club has been the people she has met rather than any particular game.
"Just making friends for life, pretty much. Even from my first year playing I'm still really good friends with a lot of those girls. They are all around the world now.
"Playing a team sport is just perfect for making lifelong friends.''
Ammundsen said she would "probably hang the boots up after this year'', but the statement did not stand up to further scrutiny.
Turns out she has said that more than once before.
"Probably two or three times,'' she chuckled.
"But it took a little bit longer to get fit this year and it takes a few more days to recover after a game.''
