Ticket sales now open: purchase a ticket
JuMP-dev 2025 will be held November 17–20, 2025 in Auckland, New Zealand.
This is the week following CPAIOR 2025, which will be held November 10–13, 2025 in Melbourne, Australia. (Melbourne is a 4 hour flight and 2 hour time difference from New Zealand.)
JuMP-dev will be co-located with the 57th ORSNZ, the Operations Research Society of New Zealand’s annual conference, which will take place November 20–21, 2025, also in Auckland, New Zealand.
Outline
The purpose of JuMP-dev is to bring together students, researchers, and practitioners with interests in the methodological, algorithmic, and software aspects of JuMP and related packages. In particular, we invite new contributors and those who have not met the core development team.
All participants will uphold the JuMP Code of Conduct.
How do I attend?
To attend JuMP-dev, you must purchase a ticket.

Venue
The workshop will take place in downtown Auckland.
Pre-conference excursion
On Sunday we will walk up Mt Eden for a view of the city.
Meet at Mt Eden Village at 2pm on the corner of Stokes and Mt Eden roads. The easiest way to get there is to catch a bus from the city. Enter the bus by the driver’s door and tag on with a contactless credit card. Remember to tag off when you exit the bus from the back door.
If you don’t want to walk up the hill, meet at the Good Home Mt Eden from 3:30pm.
Talks
The first two days of JuMP-dev will be held at the GridAKL in downtown Auckland, New Zealand.
Enter the building from Pakenham St West and turn left down the corridor.
Dinner
On Monday night there will be a dinner at Good George North Wharf.
Hackathon
The hackathon on Thursday will take place in Building 201, Room 326 at 10 Symonds street. We will use this Google Doc to co-ordinate topics to discuss.
ORSNZ 57 will be simultaneously taking place in the nearby University of Auckland Conference Centre.
Gurobi
The Gurobi Optimization Community roadshow will take place after the hackathon on November 20.
You must register in advance at gurobi.com.
Accommodation
There are a wide range of accommodation options within walking distance.
Airport transfers
The easiest way to get from the Airport to downtown is via the Sky Drive bus. Tickets are $20, and you can purchase one from the driver.
There are a variety of cheaper but non-direct and slow public transport options. You can pay for public transport in Auckland with a contactless credit card. For busses, tag on and off the reader inside the door of each bus. For trains, some stations have barriers, others have a post at the platforms.
Excursion
There will be a self-guided excursion on the Wednesday 19 November.
Option A
We will plan to catch the ferry to Devonport and walk to the summit of North Head for views over the city and harbor, followed by a walk around Devonport.
Meet at the downtown ferry terminal at 14:15 in order to catch the 14:30 ferry.
Option B
If you want a more adventurous (but highly recommended) option, catch the ferry to Tiritiri Matangi island. This island has been cleared of all introduced pests and has many native New Zealand birds. You must book tickets in advance from explore ($110 return) and take your own food.
Here is a map of the island. Oscar’s recommended route: turn left from the ferry, along Hobbs beach, up the Kawerau Track and spend time in the native forest, then back along the cable track for lunch at the lighthouse, finally down the wattle track to meet the ferry back to the city.
New Zealand entry requirements
If you require a visa, please email jump-dev-2025@googlegroups.com with the
subject Visa invitation letter.
Regardless of your visa status, everyone traveling to New Zealand must complete a New Zealand Traveller Declaration. The easiest way to complete this is via the app. You must complete it no sooner than 24 hours before starting your travel. If you forget to complete the declaration prior to traveling, you may request a paper form from the flight attendants on your flight.
