David Seymour's responding to a post evoking him as needing trimming like a lawn.
Te Pāti Māori co-leader Rawiri Waititi re-shared his partner's post showing him cutting the grass.
The caption read: 'I told him to behave as though every piece of grass is a David Seymour. The lawns are getting a good effing hiding.'
Seymour says that's objectionable - with its suggestion of attacking a person you disagree with.
