Though not as tropical as many other countries, Aotearoa is anything but short on fantastic scuba diving locations. This article will introduce you to the best diving New Zealand has on offer.
New Zealand is one of the most popular tourist destinations thanks to its grand landscape, snowy mountains, and lively cities. But not many people are aware of how beautiful its underwater world is too!
In fact, Aotearoa is home to many world-class dive and snorkel sites.
COVID-19 has come with its fair share of challenges for New Zealand businesses. Though we do our best to share accurate information, this can change quickly as some businesses make the decision to operate under reduced hours or hibernate. We suggest you double-check they are open before finalising your plans.
What to Expect When Diving in NZ
With a variety of water temperatures, enthusiasts can scuba dive in New Zealand all year round.
From June to November, the water temperatures are generally around 15-21°C. The water then gets warmer from December to May, where it’s around 19-25°C. As a general rule, the further south you travel, the cooler the ocean will be.
Pro tip: If you like to travel with your own gear, we recommend a 7mm wetsuit for most dives. If you prefer to travel light, wetsuits, BCDs, oxygen tanks and all required equipment is readily available for hire from all dive shops in New Zealand.
The North island has subtropical water and attracts tropical and large fish all year-round. Diving North Island is best from January to June as a general rule.
The South Island has cooler temperatures, but also offers dramatic diving. Diving South Island is best between November and April.
It is, however, possible to have amazing dives right across the country at any time of year.
Most of the best dive spots in New Zealand are shipwrecks, though you will also find countless reef dives across the country.
Whilst diving in New Zealand you can expect to spend time around amazing marine life, whilst also encountering unique marine animals such as sharks, dolphins and seals.
