The event began in Madang on April 8 and will run until April 17 and there is a large price tag for the first angler who lands a marlin weighing 250kg or more.
Bank of South Pacific, which is a platinum K25,000 sponsor of the event, has put up an additional K100,000 in cash for the angler who can do this.
Naturally, the Madang Game Fishing Club is delighted. Vice president Gary McGowan thanked BSP for their continued support and the "valued relationship established between the Madang Game Fishing Club and BSP".
"It's a real pleasure to work with a strong, long term sponsor who not only puts up as a platinum sponsor, but who also strives to maximise the benefits they gain from the sponsorship," McGowan said.
BSP Madang branch manager Barry Namongo said: "BSP was pleased to join the challenge this year and supporting the event encourages growth in tourism and sports in Madang and PNG as a whole."
"The National Game Fishing Titles has become popular in the sporting calendar and this was good for the country as it increases Papua New Guinea's international exposure in a positive way," Namongo said.
The National Game Fishing Titles started in Rabaul in 1974, with the New Britain Game Fishing Club being the first hosts. BSP has been the platinum sponsor since 2002.
