I though it was around the 20kg mark but will stand corrected. Went 115cm nose to fork and by 60cm round the girth. Caught on the surfcaster using a bit of squid, 5/0 gammie circle and 40lb BM tough trace. I'm told it took me about 1/2 hour to get in.
Finally got a copy. Here's a picture of the fish in question

| Nice Jw, Sounds like you will be pretty close to that mark. Not sure of a table but that sounds about right from me. Bloody exciting to catch those buggers from a boat but i can only imagine all the things going thru your mind from the rocks, No wonder you lost your sence of time. Nice catch. |

An equation I got from the Mfish website gives 17.9kg for 115cm length (no girth in the equation).
There is a table on here that uses length and girth, but starts at 173cm/66cm. Also says add 10% for a well conditioned fish.
http://www.fishing.net.nz/index.cfm/pageid/332/ViewPage/Weight+Calc+Tables - http://www.fishing.net.nz/index.cfm/pageid/332/ViewPage/Weight+Calc+Tables
17.9+10% = 19.69 = 20kg
Someone on here was asking for data a while back, I think to generate their own equation. Hopefully they will see this and be able to help.

 That great! Thanks for that. It was in reasonable but not good condition - I've seen fatter so I think between 17.9 -20kg is going to be about right.

Of course in 6 months time it will have grown a few kilos and taken me an hour to get in

In a few years it will be HUGE ... I remember telling some old sports stories to a young team I was playing with and one of the teenagers piped up with:
"The older you get the better you used to be!"
He had me there ...
(and that was more than 10 years ago now - imagine how good I would be if I was telling those stories today)

Nice fish JW and top effort from the rocks mate.
Here is the formula for imperial measurements;
Girth x Girth X Length /800
So approximate inch figures below, tranposed from your metric girth and length back to imperial, but accurate calculation ;
23.62 inches x 23.62 inches x 42.276 = 25263.83/800
= 31.58 pounds or 14.35 kilograms
Hope that helps, and remember the calculation is a guide and reference only it is not absolute and accurate as all fish have different condition, a fat fish would weigh more for example. ------------- "The sea, once it casts its spell, holds one in its net of wonder forever." - Jacques Cousteau |

Can vary greatly with kings depending on condition. Have seen 110-115cm fish varying between 14 and just over 22kg.
Got onel last year measured 120cm from memory and in good nick so called it for 20kg but in reality I will never know (or really care TBH) ------------- LedgeNZ LBG |

| 18 to 20 kg would be close, great effort on a surfcaster, it would of had a good bend on. |

| Sounds like an awesome fish off the bricks mate, yeah round 18k's i would say. have seen much shorter fish go more than that though, this time of year seems to be a real variation in condition and weight |

Nice fish off the bricks mate whatever the exact weight may have been ------------- Only when the last tree has died and the last river has been poisoned and the last fish caught will we realise we can't eat money. |

There was a fish weighed in the Blue water classic here in Tga that I believe was under length for the comp (min 1m) but weighed 21 kg which would have won the comp if it had been 'legal'!!!! As Epic said, massive variations at the moment depending on condition.
Nice fish off the bricks JW...

| Thanks. One that didn't get away and by far my biggest from shore so I was very happy with it. It was caught up at Mahurangi in November fishing into the chanel just around from the harbour mouth. Now I have to try and get a bigger one..... |

Haha I knew it was Mahurangi thats a cracking spot that one I fished it heaps and recognised the ledge. Heaps of fish cruise through there I lost a nice kingie off my yak in Nov 09 near there. Caught a few rats off there and snaps up to 14 pound off there. Its nice n easy to fish off sometimes you have to be patient there but 9 times out of ten something good turns up.
If you want to beat that fish now is the time stick a livie out there and I will be heading that way soon its still my fav spot.
