Almost half of the New Zealand population admitted to hiding clutter under cushions, behind couches, or inside cupboards or drawers when guests were coming over.
Psychologist Sara Chatwin said the results showed that while New Zealanders like to keep a clean and tidy house, daily pressures sometimes made it hard for people to attain the level of cleanliness they wanted.
"For many people house tidiness and cleanliness is directly linked to their feelings of achievement and accomplishment.
"When this lapses we can feel like 'underachievers' or failures.
"Personal standards are a large part of who we are and how we present. We feel as though we haven't 'done our best' ... and this may leave use feeling under-whelmed," Ms Chatwin said.
