Candidate registration for Kaohsiung's mayor and city council races has opened, with the campaign season now formally underway ahead of a late-November vote.

• Registration for both the mayoral and city council contests began this week in Kaohsiung.
• DPP councillor Chiu Chun-hsien was first in line, arriving before 8am with his wife and daughter to file for a fourth term.
• He brought along former local township heads and community leaders, including a former rival who is sitting this race out, as a show of cross-generational backing.
• His pitch rests on a decade of perfect attendance at council sessions and 14 separate "quality councillor" ratings from civic groups.
• He is running on continuity, arguing local construction projects should not be interrupted mid-stream.

Outlook: Voters in Kaohsiung go to the polls on 28 November, with the field taking shape over the registration period.
