Not only is she actively involved in the day-to-day running of Wairewa Station, a 1037ha hill-country property near Fairlie which she farms with her husband, Philip, but she is now out "to help improve the lot for New Zealand sheep and beef farmers".
Mrs Munro (51), who was elected Beef and Lamb New Zealand's new director for the central South Island earlier this year, is passionate about farming.
Brought up in West Otago, she married Philip Munro 33 years ago and the couple - who both have long family histories in the sheep and beef industry - have been farming ever since.
Mr Munro was originally in partnership with his parents at Mandeville and the couple farmed there for about three years, during which time their son Simon was born.
When Mr Munro's parents moved to town, the property was sold and the couple bought a 1214ha farm at Greenvale, Waikaka.
It was a time where they put their "heads down, bums up and worked like crazy", Mrs Munro said.
They were there for nine years, did a lot of development work and got the property running "pretty sweet".
Farming was hit hard in the 1980s but the ever-resourceful couple - "we were always do-it-yourself-farmers" - went into survival mode by getting together with friends and doing their own shearing.
While they now wonder how they managed to do it, it was the difference between surviving or not surviving.
One year, they worked out their shearing bill was $32.
Infant daughter Olivia (now 23) spent her early days in a portable cot in the woolshed, waking up when the machines went off.
"We like to give things a go.
We've always kept our eyes and ears open for opportunities," Mrs Munro said.
Towards the end of their time at Greenvale, they dabbled in feral goats, buying old does for $20 for weed control.
They ended up selling young does for $150 and bucks for $90.
The couple's next move was to a much larger property in Western Southland, which had a substantially better home than the small transportable bungalow at Greenvale, along with a second house, and covered yards.
They made an offer, having only looked halfway around it, and had to work quickly.
The couple always maintained that properties should be in a saleable condition.
"We've always prided ourselves on keeping our properties presentable," Mrs Munro said.
Their own farm was signed up and sold within a week and they shifted to their new home with an understanding that if it was not working for them within five years, they would sell.
It was a large farm and there were just the two of them.
There were a lot of repairs to be done.
After four and a-half years, and with the bottom dropping out of the wool industry, they decided it was too hard and made a business decision it was not working for them.
They were able to lease back the property as they began the search for a new one.
At the same time, tragedy struck the Munro family when Simon was diagnosed with cancer.
He managed to visit their new property, Wairewa Station, but died, aged 16, just before the family shifted north.
Mrs Munro often thinks that the couple's foray into ostriches was their "survival mechanism" - a distraction to help them get through the tragic loss of their son.
Mr Munro had gone to the North Island to buy a bulldozer and came back with the idea of emus, which subsequently led to ostriches, as an off-farm investment.
The couple saw it as an alternative form of red meat farming.
They were involved with the first live shipment of ostriches to New Zealand in May, 1995.
From 1993-2000, Mrs Munro was on the executive committee of the New Zealand Ostrich Association, serving the last three years as president.
"In that time, we took an obscure red meat, got it included in the Meat Act and took it to export, all within seven years.
No mean feat working through the challenging maze of bureaucracy," Mrs Munro said.
While Mr and Mrs Munro had initially ideally wanted to stay in the South, they were "quietly taken" with Wairewa Station.
They have now been at Wairewa for 16 years.
While the first couple of years were "incredibly kind" to them, before the dry hit.
The property runs 3500 Romney-cross sheep, 240 breeding cows, 60 goats and 345 grazing dairy stock.
