A Christchurch mother who refers to herself as "Mamma Doof", has vowed to fight charges of hosting underage parties.

Theresa Anne Soper, a 48-year-old demolition worker, has elected a judge-alone trial after pleading not guilty to allowing alcohol to be drunk on her semi-rural property.

She was arrested last year after it emerged she had allegedly been hosting underage parties in a barn for up to 400 teenagers at her Main North Rd property.

Soper will appear at Christchurch District Court on April 11.
