The National Party wants the Public Service Commissioner to look into government contracts given to a company run by Cabinet Minister Peeni Henare's partner.
Consultancy Tatou - until recently run by Minister Henare's partner Skye Kimura - was awarded multiple government contracts totalling around $600,000 over the past two years.
About $250,000 came from the Ministry of Health, while Henare was Associate Minister of Health.
National Party public service spokesperson Simeon Brown spoke to Ingrid Hipkiss.
