National's managed to increase its support throughout the ponytail-pulling saga, but John Key himself hasn't been so lucky.

The Herald digi-poll surveyed people before, during, and after a waitress accused the Prime Minister of harassment.

Despite the damaging coverage, the National Party has managed to slightly increase its support, up 0.6% to 51%.

Labour, on the other hand, has slipped 0.2%, to 28.7%.

It's a different story when it comes to preferred Prime Minister though, with John Key falling 0.4% to 64.6.
