New Zealand's Prime Minister Jacinda Ardern announced on Thursday that she would be stepping down from her role by February 7 after five and a half years, according to New Zealand media, DW reported.

"For me it's time," she told members of her Labour Party, making clear that there was no secret scandal behind her resignation. "I just don't have enough in the tank for another four years."

She made her announcement in a televised press conference.

"This has been the most fulfilling five and a half years of my life," local news site NZ Herald reported her as saying.

"I am leaving because with such a privileged job comes a big responsibility. The responsibility to know when you are the right person to lead — and also when you’re not," she said.

The prime minister also announced that a general election would take place on October 14.

"While I won’t be contesting the election, I know the issues that impact New Zealanders most will remain the focus of the government through this year and into the election," Ardern said.

Public broadcaster Radio New Zealand reported that she plans to remain sitting as a member of parliament until the end of April to avoid a by-election, but has no plans for after that.

Ardern led New Zealand during three years of the coronavirus pandemic. Her handling of the crisis garnered international praise with the country faring better than many others—although not without escaping criticism entirely.

She was also prime minister during one of the most violent episodes in New Zealand's recent history when a neo-Nazi killed 51 people in a shooting at two mosques in the city of Christchurch.
