United Arab Emirates airline Etihad has a 10 per cent stake in Virgin which will also be slightly diluted.
As part of an offensive against Qantas, Virgin Australia issued new shares to Singapore Airlines for A$105 million, using most of those funds for a proposed 60 per cent stake in low-cost carrier Tiger Airways to take on Jetstar.
It also will buy all of regional carrier Skywest Airlines.
Parton said Air New Zealand regarded the deal as a good one.
"From an investor perspective we have a lot of confidence."
The Tiger deal is subject to regulatory approval and competition issues have been described by the Australian Competition and Consumer Commission as "very complicated".
Virgin Australia chief executive John Borghetti said the deal was part of Virgin's aim of being the airline of choice in every sector of the market.
Borghetti said, "Virgin competes with a lower cost base."
