A Hutt Valley man has pleaded guilty to the manslaughter of his baby daughter in 2009.

Tawera Wichman, 24, appeared in the High Court in Wellington by video-link from Auckland and admitted killing the child by assaulting her between March and September in 2009.

Teegan Tairoa-Wichman was 11 months old when she died.

Justice Williams convicted Wichman and remanded him on bail until his sentencing next month.
