NZ First leader Winston Peters has defended a clause in the party's constitution which hold MPs liable for a $300,000 penalty if they resign.

The clause states that every member who is elected as a New Zealand First list MP or constituency MP, must sign a "resignation obligation contract"

Winston Peters told Mike Hosking the clause will not silence a wide range of views.

" I have had people vote against the euthanasia bill from the party, unless we are at least 90% in agreement we won't go down that pathway."
