Hung Hsiu-chu, the only participant for the ruling Kuomintang party's primary Taiwan leadership bid, has passed the required support in public polls with an average rating of 46.2 percent.
The results, released on Sunday, are based on three polls conducted by different pollsters on Friday and Saturday, with each required to collect 1,200 valid samples.
Hung, deputy head of the island's legislature, had to secure at least 30 percent support in the polls, otherwise the party would look for another candidate. Hung's nomination still has to be confirmed by a convention of KMT party delegates next month.
The opposition Democratic Progressive Party endorsed the candidacy of its chairwoman Tsai Ing-wen for the 2016 election in April.
