Swim caps & start groups

As part of your swim pack you will receive a silicon swim cap. Each start group has a different coloured cap. Start groups are determined by the speed group you selected in the entry form. If you have swum with us already this season please bring your cap to minimise the number of caps you collect and reduce our environmental footprint.

The start groups are calculated by our operations team and are organised by speed groups & entry numbers. These can vary from event to event, unless you are a Multi Event pass swimmer, and we are reluctant to change these as it can affect results.

Speed 1 & 2 – Fastest swimmers

Mid 1 & 2 – Competitive but like a little bit more space on the start line

Comp 1 & 2 – Out there to challenge yourself and swim with friends and family


Live results will be available as soon as you have crossed the finish line. If you can not see your result or think there is an error please come and see the team in registration as soon as possible and definately BEFORE prizegiving.  You can find the results here. 

Post-event nutrition

Once you have crossed the finish line one of our awesome crew will be there to meet you with water and a Banana.

BYO drink bottle

As part of our goal to have a greener footprint, we will no longer be offering drinking cups so please remember to bring your own drink bottle. Thanks to the awesome team at the hydration station, you can fill your bottle with  water. Look out for our water station and stay hydrated!

Amphibian details

The Amphibian is back for 2025 AND ONLY IN ROTORUA!

This event gives you a new perspective of the beautiful Lake Tikitapu.
Collect your event pack from registration, & bring a small bag to place your running shoes, small towel and running shirt (if needed) for the first transition. There will be a designated area at the main event site to place your bag, then these will be taken to the first transition area at the top of the lake.

We recommend that you wear a swim/run suit so that you can complete the entire Amphibian wearing it saving you valuable time. You can wear a full wetsuit if you wish. All belongings will be brought back to the event site, once the transition area is cleared of all participants. Note: this will not be in time for your second transition.

The event sees you starting from the main event site with a 1.7km swim, straight up to the top of the lake. There you will exit the water to the transition area where you can put your running shoes on and head up the steps to begin the run. You will need to keep your cap and goggles with you. The course will take you around the lake, on a 3.5km run back to the main event site to a second transition. There you can ditch the shoes and run back in for another quick splash of 500m and then head through the finish line archway to the cheers of your friends and family.


All Banana Boat New Zealand Ocean Swim Series events are patrolled by trained lifeguards and first aid qualified personnel who are present to assist you at all times.

So that the events are safe and enjoyable for all swimmers, there are some rules for the event. Find out more here.
