Tongariro-forum threads on September crossings are direct this still counts as winter conditions, posters calling the route genuinely cold, wet and windy the default expectation rather than the exception, even a clear, settled morning capable of turning within an hour. One hiker reported fine enough weather to walk in shorts on their September date, while another attempting the crossing around the same time hit genuine rain and accumulation instead, underscoring how much day-to-day variation exists. Regulars are consistent a professional guide is essentially mandatory, the alpine section requiring real winter gear including an ice axe and crampons given the genuine avalanche risk after a heavy system. Posters call checking current conditions and guide availability essential before committing to a specific date. The record: 9.1C days feeling like 6C, 0.7C nights, an extraordinarily high 175mm across nearly 21 days, a notably high 4.6cm of fresh accumulation and 89 percent humidity.

A New Zealand forum thread comparing Napier to the Bay of Islands for a June trip pointed out that the east coast, sheltered by the older ranges inland, stays drier than a lot of the North Island through winter - you get drizzle rather than proper downpours. Daytime highs land around 14-15C, matching what other posters described, and nobody's swimming or kayaking this time of year. It's really a wine-and-food-trail season instead: cellar doors and restaurants stay open, you just need a warm layer and won't be on the beach.

Hawke's Bay is known as one of New Zealand's sunniest, driest regions, but December is spring turning into summer rather than summer proper: the forum describes it as capable of being cool and wet, with spring showers continuing, and the record agrees at eleven rain-days against 23°C days and 15°C nights. Regulars pack a warm jumper, long trousers and a light rain jacket for the windy, showery days. That warmth matters locally — it is what ripens the fruit for Christmas. If the wineries and Art Deco Napier are the draw and the dates are open, February is the month the forum names.
