Labour has not held its annual get-together in Dunedin since 1988, and local MPs are planning a show of what the city has to offer.
Dunedin North MP David Clark said conference venues were often decided for pragmatic reasons such as the number of local delegates and ease of transport - hence the 30-year gap between conferences.
However, Dunedin was now easier to get to and local members were enthusiastic about hosting the gathering.
"We're keen on getting as many people here as possible and showing off what we have.
"We see it as an opportunity to showcase the city as well as celebrate with the party what we have achieved so far."
Dunedin South MP Clare Curran said when she and Dr Clark pitched two years ago for the city to host the conference, they had highlighted the special characteristics Dunedin had.
"We're providing a list of all the main local places to visit and on the Sunday before the leader's speech there is a 1½-hour break where we will be offering tours."
The conference, being held at Dunedin Town Hall, opens tomorrow night with a civic welcome from Dunedin Mayor Dave Cull, and short speeches from Labour party president Nigel Haworth and Prime Minister Jacinda Ardern.
On Saturday, Prof Haworth, deputy leader Kelvin Davis and Finance Minister Grant Robertson will deliver major speeches, before the party meets in closed session to discuss its policy platform and hold elections to the party council.
On Sunday, Ms Ardern will make her leader's speech, an event which will be open to the public.
•The party is looking to establish a new branch in Queenstown.
A meeting will be held in the St John building in Frankton tonight to see if there is enough interest in setting up.
Party member and meeting organiser Gordon Dickson said it was an opportunity for people to discuss issues in the area.
