This isn’t the cheapest of the many tours in Kaikoura, but we enjoyed it and found it to be good value for money.
We liked the fact that if you don’t see a whale, they will refund 80% of the ticket. We reckoned that meant they must be pretty confident and indeed it turned out be the case.
We saw a sperm whale very close, and many many dolphins, also albatross. The guides were witty and informative. They do warn about seasickness and there were some who were but I recommend this trip heartily.
