Stoned-Em Sounds Summer Slam 2025 spearfishing competition.

5th-7th December 2025

This is our 7th year running New Zealand's biggest spearfishing competition and we are back with a new format with a three day event!

T o be eligible to win this years major spot prize you need to get 2 of the 7 species listed below and collect some ocean rubbish.

The boundaries of this three-day event are the Marlborough Sounds area, which covers a massive 4000 km2 and competitors can either shore dive, use a kayak or boat.

Looking after the marine environment that we all enjoy is a key part of this competition, so the ocean rubbish categories will be a prominent feature again with some awesome prizes lined up.

Competition T-shirts & Singlets will be for sale with your ticket purchase, these will be limited to online sales only this year and as usual all profits go to this years charity, Project Jonah.

The species list has been mixed up and the 7 species for this year are:

Kingfish

Crayfish

Moki

Snapper

Flatfish (sole,flounder)

Mystery species 1 – announced at the briefing

Mystery species 2 – announced at the briefing

The scoring is designed so the number of species entered will win over weight. Therefore, you are encouraged to target the different species rather than ‘up-size’ your catch.

The weigh-in is on Sunday 7th December at Marine and Outdoors (14 Horton Street) from 1pm with a cut off at 3pm, so make sure you are be lined up with your catch by then to be eligible to enter.
