KEY POINTS:
The Abel Tasman Seal Swim provides the opportunity for swimming with fur seals in the Tonga Island marine reserve near Nelson.
The reserve is a breeding ground for the seals and the tours from November to May enable visitors to see the seals at various stages of the breeding and birth cycle.
Pups arrive about December. Those who don't want to swim can watch from the boat or island.
