''I eat, breathe and sleep Beef and Lamb,'' Mrs Munro, a South Canterbury sheep and beef farmer, said, laughing.
But change is in the wind and, after serving two terms as farmer-elected director representing the Central South Island, she is standing down.
Nominations are open for two director positions - for the Western North Island, where Kirsten Bryant, who has served two three-year terms, is seeking re-election, and the Central South Island.
Nominations close on December 18, with voting forms posted to registered voters in the two electorates in early February.
When Mrs Munro announced her intention to stand back in 2010, she said she would stand only for two terms.
Her reputation and integrity were important to her and, since then, she had always been mindful that was what she had said and so that was what she would do. But it had still been a hard decision to make, she said.
She was mindful that Beef and Lamb chief executive Dr Scott Champion was also stepping down, after nearly 10 years with the organisation, leaving at the end of March.
She had to question whether it was a fair time, for both the board and management, for her to stand down. She was also conscious of succession.
Life was busy for Mrs Munro and it had been a shared effort by both her and her husband Philip on their 1037ha hill country property, Wairewa Station, near Fairlie.
While a staff member was now employed, it was also time to consider her home and her business. It was also about ''sharing the load'' and there was some real talent in the agribusiness sector.
''I'm really confident there is an opportunity for a male or female to come forward and do their bit for the organisation. After all, it's as we say, it's by farmers, for farmers.''
What the Beef and Lamb team, both governance and management, had achieved over the past six years was ''pretty darn impressive'', she said.
Support had been lifted more than 30% through the referendum, with the organisation given a strong mandate to work on behalf of farmers for the next six-year sheepmeat and beef levy cycle.
The challenge for incoming directors was to maintain that support, if not improve on it, she said.
Not long after Mrs Munro joined the board, Meat and Wool New Zealand became Beef and Lamb New Zealand.
She believed there was now greater awareness of Beef and Lamb and of what it did for sheep and beef farmers.
''I think we've lifted farmers' perception of exactly what their levy does for them.''
''I feel very privileged to have had the opportunity to represent my fellow farmers and hopefully I've done them proud,'' she said.
She was particularly proud of the ''regionalisation'' of the organisation and she enjoyed the three-way connection, of each farmer council, extension manager and director working together.
Mrs Munro enjoyed working alongside meat-industry representatives on the board, saying that had been insightful and helped with ''understanding the bigger picture''.
Challenges remained in the red-meat sector and it was important Beef and Lamb delivered field days that were appropriate to help farmers.
''We've just got to keep working at it and keep communicating and trying to find improved ways of doing things,'' she said.
Compliance challenges were not as prevalent when she first joined the board and they were having a real impact on the way farmers farmed. It was important farmers engaged and did their part to improve health and safety, and in nutrient allocation and water quality.
Brought up in West Otago, Mrs Munro has been farming ever since marrying Philip.
''I'm always told I'm a passionate person, in regards to farming and agriculture, so I guess I must be,'' she laughed.
''Sheep and beef farming's not for the faint-hearted.
''Farming's not. It's just something in our DNA, isn't it? We just keep on keeping on,'' she said.
While Mrs Munro was stepping down from the board, she was ''not going away'' and she would be keeping a close watch on what was happening in the industry.
She hoped farmers would think seriously about the opportunity to stand as a director - ''nothing ventured, nothing gained'' - and she was happy to discuss the role with anyone that was interested.
