The company got caught with costs, such as deposits on the venues.
"It's not good. We can go into liquidation with the Rugby World Cup company 3D Live, which is no longer active, but we can carry on with our other company providing 3D programming and holograms," she said. "So far [creditors] have been very understanding.
"We knew there was always a risk ... we've lost a lot of money. We were looking for 75 per cent [advance] ticket sales," she said. "It's a very different culture here. New Zealanders would wait to see if the All Blacks were in the final before buying the ticket and leave it until the last day - we could not operate like that."
The couple were "seriously" out of pocket, she said.
"We should never have gotten into it without sponsorship. Decisions on contracts had come through very late ... and there were a lot of rules and it became really, really hard getting sponsors.
"We put a couple of sponsorship deals on the table which were not acceptable to the Rugby World Cup company.
"Rugby World Cup rejected them, not wanting it to conflict with their own sponsorship deals."
Overseas 3D coverage of last year's soccer World Cup was built around sponsorship by electronics company Sony and was designed to hurry the uptake of 3D TVs.
"That is what should have been negotiated [when] they started making deals. When people started signing up deals with Rugby World Cup, 3D was not an issue," Ronel Shodt said.
RWC 2011 general manager Ross Young said there were challenges getting the Shodts' "self-funding" plan to work.
Sky TV chief John Fellet said that with the end of the deal, there were no plans for 3D TV coverage for about 7000 sets capable of receiving a 3D picture in New Zealand.
He predicted 3D coverage or "super high definition" - offering pictures four times as sharp as standard HD - would become more common.
