The company's "belated birthday sale" will see a range of promotional flights released from Wednesday this week.
Customers will be able to pick up a one-way flight between Auckland and Dunedin for $49, Auckland and Queenstown for $49, and Wellington and Queenstown for $39.
The sale does not include flights for the school holiday period.
Travel dates for the sale include mid-August 2020 to mid-September 2020, mid-October 2020 to mid-December 2020 and mid-February 2021 to mid-March 2021.
This follows on from a promotion the airline launched at the beginning of the month when the airline returned to local skies.
There has been strong competition between Jetstar and Air New Zealand, with both airlines looking to capitalise on domestic tourism.
Like all operators in the airline and tourism industry, Jetstar has been hit hard by the impact of coronavirus.
In March, Qantas and Jetstar announced they would stand down 20,000 staff due to the impact of the virus.
The airline is aiming to reach 60 percent of its normal domestic schedule, operating 75 return flights per week to Auckland, Wellington, Christchurch, Dunedin and Queenstown.
The airline said it would closely monitor demand, with further domestic flights likely to be added to the schedule in coming months.
Jetstar's promotional fares include:
• Auckland to Wellington from $32 one way
• Auckland to Christchurch from $34 one way
• Christchurch to Wellington from $32 one way
• Auckland to Dunedin from $49 one way
• Auckland to Queenstown from $49 one way
• Wellington to Queenstown from $39 one way
