Well before she was president of Stop the Stadium, Bev Butler found a typographical error in a list of figures 142 pages into a 162-page Carisbrook Stadium Trust report, showing the estimated economic impact for Dunedin, and rang the Otago Daily Times.
When a story did not appear in the newspaper the next day, she rang to find out why, complained the story had not been published immediately, and demanded the name of the person who made the decision.
Organisations from the Carisbrook Stadium Trust to the city and regional councils, not to mention the offices of the Ombudsmen and the Prime Minister, have heard from Ms Butler since that time.
Many have privately - and once, by mistake, publicly - expressed their frustration with her approach, but Ms Butler makes no apologies.
"I don't know if I'd describe myself as combative, but I'm persistent, especially when I see that something is wrong and I think that something should be done about it," she says.
There is an undeniable passion in her belief the stadium is the wrong choice for the city, and that there has been a corruption of the process by which organisations like the Dunedin City and Otago Regional councils, and the Community Trust of Otago, have gone about putting the project in place.
There is a clear frustration that her questions have not, she believes, been answered, and that her organisation's message has not been properly aired.
"It's been difficult - now that you have brought up the ODT - I feel that it's been difficult to get our message out through the ODT. I'm sorry if that offends the ODT, but I feel that there have been lots of issues on the way that should have been dealt with in a more investigative way."
While her first foray into local politics was not a success - she joined former city councillor Lee Vandervis' Open Democracy party before the last election but attracted just 282 votes in the Hills ward - she has had far more success with her anti-stadium lobby group.
What began as one woman with a mission has become an organisation boasting 1434 financial members, intent on halting a project that could cost city and regional council ratepayers almost $130 million, not to mention interest estimated last year at $183 million.
So who is Bev Butler, and why has this particular project become such an all-consuming passion? Born in New Plymouth in 1955, the 53-year-old completed her secondary schooling at Sacred Heart Girls College.
Her two children also attended Catholic schools, and she says Catholicism imbued in her the importance of social justice.
Ms Butler completed a degree in mathematics, a subject for which she says she has always had a natural flair, at the University of Melbourne in 1977, after moving to Australia in 1973.
She met her husband, Peter Attwooll - now also a passionate anti-stadium campaigner, in Melbourne. The pair married in 1979 and returned to New Zealand the same year.
After positions including a stint with the Ministry of Transport in Wellington, she trained as a teacher, and she and her husband worked in the profession, and had two children along the way, before moving to Dunedin in 1993.
The year before, the family had come to the city on holiday, arriving on a drizzly day, but 3were taken by its historic buildings.
"We got out of the car, looked around, and said 'let's move here'. A year later, we were here. We moved here with no job. We knew no-one."
Since then, she has taught part-time at Kaikorai Valley High School, spent nine years at the University of Otago, where she became head of mathematics at Foundation Studies, and runs a successful private maths tutoring business.
In 2005, she spent a year teaching in Kazakhstan, which she describes as "one of the most corrupt countries in the world", where she ended up teaching not only the children of diplomats and United Nations officials, but the offspring of Russian mafia figures, some of whom had personal bodyguards.
While Dunedin cannot boast that level of political dysfunction, Ms Butler believes the city's institutions have not acted properly in relation to the stadium, and says the story the city is being fed is far from the truth.
What is at the heart of your opposition to the stadium?
"Maybe I don't really believe what they're saying. Maybe that's at the heart of it. I believe that the people of Dunedin have been misled over this whole project."
But why does that press your buttons? Many people may believe that, but they don't set up large organisations to oppose it.
"Because I see that this could be so detrimental to the city. I really love this city. I see that this project is going to be so damaging to this city, and will affect so many people on a personal level.
"There are many things in the world that need to be fought; there's starvation, climate change, there's all these different things, but I personally cannot fight all of them, and when I put my energy into something, I prefer to put it into that main thing, and really fight that, and I guess this is something local, something I can do something about.
"The city is already considerably in debt, and when I look at the figures it really does concern me. Look at Dunedin City Holdings Ltd - they are borrowing money to give to the city council to go about their everyday business.
"I think they gave last year about $20 million, and their profit was only $6.8 million, so the city is living off borrowed money, and eventually things will catch up with them.
"The stadium's just another example; it's borrowed money. It's different to the Town Hall. That was money the city actually had. There are a lot of people who really struggle to make ends meet, and with the increase in rates they are going to struggle even further, and especially in the present economic climate.
"This money, $140 million of public money, even if there aren't any cost overruns, could be used to benefit more people in the city instead of just a few, and I think that this is being pushed by a group of self-interested people - and that really does anger me."
Who are the self-interested people you say will make something out of this?
"Well, there's the [Otago] rugby union. They are technically insolvent. They owe the city $2 million, they owe the bank $4 million, and they will benefit from it. The land owners [at the stadium site] will benefit from it, the consultants will benefit from it."
The Awatea St land owners - do you think they made a huge amount of money?
"Oh, I think they made an enormous amount of money. I don't know exactly how much they have made, but it will eventually come out. The land would have been sold for well over market value."
You have brought up conflicts of interest regularly. Would you say there is corruption going on?
"Corruption is a very strong word, and I know I have to be very careful in using that word, but I am comfortable in saying that there is definitely corruption of the process."
People accuse your group of being too negative - is that fair?
"I think what we're doing is very positive. I feel very positive about stopping such a negative project. This project is negative for the city. It is not multipurpose. They have spun this right from the beginning."
What are your tactics from here?
"I think, ultimately, the councillors need to understand what's been going on really, and they're the ones that will have to vote against this, so I'm hoping that more people will speak up instead of just talking through me.
"There are a lot of prominent people in the city who are very strongly against it, but are not speaking up, and I think that's quite sad for the city.
"I understand that they don't want to speak up because the people pushing this project have a lot of power and many of these business people are concerned that it will impact on their business interests, and I think that's very sad for the city that we are in that sort of situation."
How will it impact on their business interests?
"Because the people pushing this project have a lot of power, and they can make things very difficult for other business owners."
Would it be unfair to call you a conspiracy theorist?
"Well, what do you mean by a conspiracy theorist?"
Someone who sees conspiracies going on, very unethical and almost illegal things going on in the background.
"I wouldn't say that I think there's necessarily illegal things going on, but I do think there are things going on that are just not right.
"For example, with information being withheld, this has been a battle that I've had all year trying to get information out to the people, to the public, where information has been withheld under false claims of commercial sensitivity, like, for example, the peer reviews.
"They [The Carisbrook Stadium Trust] never intended the public to see those peer reviews and it was only through going to the Ombudsman that they were released to the public, and they were very damning of the project.
"I didn't believe that the project would go on for this long, especially after that March 17 meeting. It should have been knocked on the head definitely then. And this is continuing to go on.
"It's taken me three months to get from [Otago Regional Council chief executive] Graeme Martin that the ORC councillors never discussed the peer reviews.
"And I am still trying to get out of the ORC information relating to whether the ORC councillors received the peer reviews."
