Riverstone Holdings Ltd director Bob Robertson, of Wanaka, said last week there had been comments made since the visit by Conservation Minster Nick Smith the project would be bad for Te Anau.
However, Mr Robertson said he and his team believed the monorail would be the single biggest way to improve commercial activity in Te Anau.
Riverstone's parent, Infinity Investment Group, also had a strong track record in raising funds and attracting bank funding and investment capital for $100 million projects and bringing them to completion.
Mr Robertson said 300,000 and 400,000 passengers were projected in the first five years. The monorail would need 12% of the existing visitors to Te Anau to be viable.
''What Te Anau has got and relies on now is through-traffic, which mostly stops for a comfort stop or a coffee on the way to somewhere else.''
Investors required third party verified documentation on the project's viability before investing.
However, Infinity was used to the process and to raising $10 million to $50 million ''all the time'' for ventures of $50 million to $100 million.
The most Infinity had raised to date was $172 million for another completed project.
Mr Robertson said he had already spent $5 million ''out of my back pocket'' on the monorail and he expected to spend another $2 million to $3 million before going to the market for more funding.
Once the monorail was established, Infinity would spend $1 million to $3 million on international marketing for the town of about 2000 as the monorail destination. It would also highlight
Queenstown and New Zealand as a whole, to bring the tourists to the country in the first place, Mr Robertson said.
''We'll work with two or three or four other main tourist activities that are in New Zealand to make it a trip for somebody for what we promote.''
''We're promoting New Zealand first, then we'll be promoting those other activities, then Queenstown, because that's the start of our project and then we'll be promoting our trip, but the biggest part of our promotion will be on Te Anau and what you can do at our destination.''
Connecting trips by road and boat, lake cruises, Glow Worm cave tours, Fiordland Cinema, fishing, hunting, plus walks, cycleways, cafes, bars, restaurants and accommodation were among the Te Anau attractions and services the monorail would promote in a visit lasting days.
''If you look at Infinity in terms of Wanaka, we were the main promoter and sponsor and creator of events in Wanaka for 10 years.
''We marketed Wanaka on TV nationally for months and all of the activities you can do in Wanaka.
''We have a production house that can do marketing and advertising, We created all of the big events that are now in Wanaka and not only did we sponsor them, but our staff did all the work.
''What's going to happen when we've got a sizeable business ending in Te Anau and its operational hub is in Te Anau?
''If Te Anau objects to everything then it's only going to get what it's got and if it's not happy with what it's got, then it needs to look at itself and say what do we really want?
''Do we want to be a destination, or do we want to be a through-stop; I don't think there's anyone else on this planet who's going to market Te Anau like we would with the monorail.''
Riverstone was in the process of answering questions of clarification posed by Dr Smith on issues including viability, he said.
The minister has yet to give his decision.
