No, there are no direct flights from the UK to New Zealand. One of the most popular airlines that operate the UK to NZ route - Air New Zealand - has flights from London and Manchester to Auckland and Christchurch, however, it always involves at least one transit airport. You can choose to have a stopover in the US, Canada, China, Hong Kong, Korea, Singapore, or Japan. Likewise, other airlines that serve the UK-NZ route (American Airlines, British Airways, Emirates, Cathay Pacific, Korean Air, Qantas, Singapore Airlines, and Qatar Airlines) offer only 1-stop or multiple stops flights to New Zealand.
