Leader David Seymour last week joked about blowing up the Ministry of Pacific Peoples - comments he refuses to apologise for and defended in the House for the second day running.
He's now also had to front on how his party vets candidates, having selected a few who've expressed some extreme anti-vax views.
Giles Dexter reports.
