A by-election was held in the New Zealand electorate of Botany on 5 March 2011. The seat was vacated by former National Ethnic Affairs Minister Pansy Wong, who announced her resignation from the New Zealand Parliament on 14 December 2010 following allegations her husband Sammy had misused taxpayer money in relation to overseas travel. The seat was won by Jami-Lee Ross, retaining the seat for the New Zealand National Party but with a 27% reduction in majority.
