Kiwi Oscar winner Anna Paquin and her husband, Stephen Moyer, have landed in Wellington - lending some heavyweight celebrity endorsement to the Greens.

The True Blood co-stars are in New Zealand with their almost 2-year-old twins Poppy and Charlie.

Paquin grew up in Wellington and she and her family are understood to be staying with her mother.

Paquin has been tweeting support for Greens Party co-leader Russel Norman and offered to help put up election hoardings. Paquin's sister, Katya, is Norman's partner.


Moyer went a step further in his support, posting pictures to his Instagram account of defaced National hoardings.

"One of the great joys of driving down to Wellington town every day is seeing how the National Party posters have been defaced," he wrote.

Moyer has also been getting back to his childhood.

"Am more excited by my bro-in-law's Hot Wheels collection than a grown man ought to be," he tweeted.

When asked by fans on Twitter if she was working in New Zealand Paquin replied: "Nope, no work. Just family time." The 32-year-old and her husband, who met on the set of the cult vampire hit True Blood in 2008, have just finished filming the seventh and final series.

They married in Malibu in August 2010 and their twins were born in September 2012.
