Air New Zealand last year built up a 19.9 per cent stake in Virgin, and the airlines share a transtasman alliance.
"With our transtasman alliance with Air New Zealand a large part of all this is bringing our product into line so it is consistent with our partner."
Aircraft cabins were being refurbished by Air New Zealand in Christchurch and should be complete by the middle of the year, Lippiatt said.
Pacific Blue withdrew from New Zealand domestic routes 18 months ago, but Virgin Australia maintains a workforce of 560 in New Zealand.
There were no plans to expand routes at this stage, Lippiatt said.
"The priority at the moment is bedding in the new product and brand. It's a process of raising awareness of who we are and what we are."
Brent Thomas, retail director at House of Travel, said that although the corporate market was not big for transtasman flights, the improved services would be welcomed by business travellers.
"I think there's scope in it for them. Their service offering is stepping up; the branding will resonate with more passengers than before."
