"While there is a lot of serious business to be discussed, we are also hoping to promote Wairarapa to delegates.
"There's a lot going on around the region, and we hope they will decide to stay a few extra days and enjoy what Wairarapa can offer," he said.
The candidate selection will see four hopefuls vying to fill a vacancy created by the retirement of incumbent Wairarapa MP John Hayes.
First to declare his hand at seeking the National nomination was winery owner Alastair Scott, 48, who unofficially entered the race last year. He had put his name forward for Wairarapa in 2011 but later withdrew and unsuccessfully sought to become National's candidate for the Rimutaka seat.
Mr Scott owns Matahiwi Winery on the outskirts of Masterton. In February Apiti farmer Jo Hayes, 55, confirmed she would be seeking the nomination.
Mrs Hayes - no relation to John Hayes - farms in partnership with her husband Pat but was born in Eketahuna and has family living in Masterton.
Two other men bidding to become the party's nominee are Richard Townley, 34, of Wellington and Masterton-born James Perry.
Both have been nominated but under the party's rules have been muzzled from discussing their nominations, a rule that applies from the close of nominations until after the selection meeting. The name of the successful National candidate is expected to be made available late Friday prior to the other conference business getting underway. Whoever gets the nod will be charged with staving off the challenge of Labour candidate Kieran McAnulty and Green Party's John Hart.
