The Prime Minister's mission to China has again been plagued by questions about one of his senior ministers back home. Kiri Allan has denied ever treating staff poorly after it was revealed some public service agencies have flagged concerns about the environment in her office. The Department of Conservation has confirmed a staff member ended their secondment in the minister's office early, due to problems with workplace relationships. And the National Emergency Management Agency's chief executive has confirmed he was aware of concerns regarding relationships in the office. Kiri Allan was back in Parliament today after taking mental health leave. Speaking to media in Shanghai today, Prime Minister Chris Hipkins denied the issue has overshadowed his trip to China. The Prime Minister was then quizzed about whether he'd need to call an early election should he lose any more ministers.
