Hi Vivien
I might just be a couple of months late, but let's try anyway.
I'm a Danish novice spearfisher and very enthustiastic about the sport. I've just bought tickets going from New Zealand to Tonga (leaving the 24th of april) to to dive and spearfish for a month (yeeeah

)
If you af still there and keen on teaming up, that would bee sweet as gold. If not, you've problably gotten back with tonnes of good memories, stories and recommendations from the prime diving spots in the islands.
Perhaps you got to know some people or a freediving community? Anything would be a great help.
All the best
