Helen Pollock's early works were created from clay and pit fired, mimicking ancient techniques and subject matter. An early work 'Interlocking Forms' won the national competition 'Ties that Bind'. Her work then moved to larger installations: 'Storehouse' at the ASA Gallery and te Tuhi.
Following her father's role serving on the Western Front in 1918, she created 'Falls the Shadow' first exhibited at the Auckland War Memorial Museum and then permanently installed at the Passchendaele Memorial Museum in Belgium.
'Victory Medal' exhibited in a gun emplacement at Narrow Neck, subsequently toured provincial museums in NZ before being exhibited at WW1 Centennial installations in three battlefield towns in Europe: Arras, Messines and Le Quesnoy.
