Shyla Parikh, aged 4, and her twin 8-year-old sisters, Sia and Dia, have politely turned down a reminder to vote at next month's general elections.
The Mangere youngsters received enrolment letters from the Electoral Commission, saying if they qualified then they were required by law to apply to be on the electoral roll.
The twin girls have drafted responses to registrar of electors Erin Temu.
"Hi Erin," said Sia, "I am too young to vote but if I could vote I would vote for Jacinda Ardern because she is charming and beautiful."
The Labour leader has also won over twin-sister Dia, who wrote: "Hi Erin, I would like to vote for Jacinda Ardern because she is kind and helpful."
