Acting group communications manager John Tulloch told the Otago Daily Times yesterday the product was designed to appeal to large volume mail senders but was expected to be received well by customers.
While unable to expand in detail, Mr Tulloch said the product went well beyond "postal email".
NZ Post was working on ways to ensure the secure delivery for receiving a critical document and ways for people to pay their bills on one site, rather than having to move out of the NZ Post site.
The digital product was part of changes being considered as NZ Post pondered the future of its mail delivery service.
The state-owned enterprise has warned it wants to change its Deed of Understanding concerning the delivery of mail and chairman Michael Cullen had written to State-owned Enterprises Minister Tony Ryall outlining some key strategic issues.
Mr Tulloch, on his way to Invercargill to attend a Grey Power conference, assured the Otago Daily Times that no changes to the country's mail delivery services would be rushed into action without consultation with the wider community.
However, he did warn that changes would have to be made.
The alternatives were significant and frequent price increases.
"We are only seeking the flexibility now so we can make the appropriate changes in the future.
"There will be nothing drastic - significant changes would be years rather than months away."
Mail volumes had been steadily falling from 1.1 billion pieces of mail delivered in 2002 to 800 million now and an expected 600 million in 2018.
Fifteen percent of NZ Post's customers sent 90% of the letters posted each year and cash flow was critical to them.
Those large clients were moving as fast as they could to digital strategies but also wanted to continue using physical mail deliveries.
NZ Post was consulting widely with those large users and the initial feedback was that they could see changes coming and wanted to be involved in the process, Mr Tulloch said.
If NZ Post did nothing to change its processing and delivery systems, postal losses would start at $10 million by 2015 and balloon to more than $20 million the next year and keep growing.
As a group, NZ Post had a "solid business" but the board had ruled out cross-subsidisation as it would degrade the total businesses, especially Kiwibank. Credit ratings could also be affected, he said.
Mr Tulloch and the group's government and community relations manager Peter Fa'afiu were attending the Grey Power conference in Invercargill to explain the changes being considered by NZ Post.
The elderly were concerned that changes would be sprung on them suddenly, Mr Tulloch said.
"There will always be a need for a physical network but the nature of what it will be will change. Rather than taking something away, we want to be in the position to provide substitution."
Also being consulted were Federated Farmers, Rural Women of New Zealand and the Dairy Women's Network.
Those groups were worried about changes to rural delivery services as the contractors delivered more than just mail.
Rural concerns were a large part of the discussions with Communications Minister Amy Adams, with shareholding ministers Finance Minister Bill English and Mr Ryall representing rural electorates.
A discussion document on changing the deed would be submitted to the Ministry of Economic Development later this year followed by a period for public submissions.
Other changes that might be considered by NZ Post in the future were locating agencies or franchises in supermarkets and service stations.
A successful agency was already operating in a North Island service station.
Also, kiosks where people could pay bills by eftpos might be considered.
NZ Post was reintroducing stamp machines, promising they would be more sophisticated than the ones of the past, Mr Tulloch said.
