Joniston, 51, who is also Sabah Journalist Association president and Kiulu PBS vice-chief replaced Datuk Louis Rampas, who is not defending the seat to allow young blood to rejuvenate the party leadership.
A former journalist with the Malaysian National News Agency (Bernama) and local newspaper Sabah Times in the early 80's, he is is among the four new faces in the BN component, Party Bersatu Sabah (PBS)'s list of candidates.
Meanwhile, PBS earlier said it would reveal the full list on Tuesday after their supreme council meeting.
Party president Tan Sri Joseph Pairin Kitingan when announcing this latest change-up, said the decision was made based on various factors but believed the injection of fresh faces will help BN in the long run.
"It is normal that various personalities might have their own supporters from their areas, but what is important in the end is that the candidates selected are first and foremost the representatives of BN," he said.
The other three new faces are businessman Joseph Paulus Lantip who will contest in the Inanam state constituency, Tokoh Guru Kebangsaan (national model teacher) Datuk Mary Yap Kain Ching who will vie for the Tawau parliamentary seat and People's Development Representative Fung Len Fui who will stand in the Sri Tanjong state constituency.
