On its domestic network it flies the main trunk using A320 jets to Auckland, Wellington, Christchurch, Dunedin and Queenstown.
A spokesman said the briefing today would be more than an expansion of its existing network.
Airports around the country have actively courted Jetstar in the hope it will fly to the regions and increase competition.
In 2013 the Business Herald revealed the budget carrier was assessing the viability of flying to the regions, using turbo-prop planes operated by Qantas on its regional routes in Australia.
Since then Jetstar has consolidated its jet network, claiming a market share of about 17 per cent by passenger numbers. The airline has carried close to nine million passengers on its domestic flights and is popular with leisure travellers in particular.
Air New Zealand has had a stranglehold on flying to regional centres but this year pulled out of three of its smaller destinations, Kaitaia, Whakatane and Westport and announced it would close its specialist regional subsidiary, Eagle Air and put on bigger planes to its remaining destinations.
Jetstar would also likely serve the bigger centres if it opts to get into regional flying.
