The latest Pokemon Go Gen 3 news has confirmed that a lot of new Pocket Monsters can now be caught.

Around 20 Gen 3 Pokemon make up the new launch, which are all part of the ongoing Christmas event.

But what you might not know is that there’s also one new regional exclusive, as well as a shiny variant, available to be caught.

Trainers are now confirming that Relicanth is a New Zealand regional exclusive.

Relicanth has been compared to Omastar, both being water-rock types which are top choices for select Raids.

Niantic have not confirmed that Relicanth is an exclusive, although it appears impossible to currently grab the crustacean anywhere else in the world.

But while you may be a little disappointed that you’re missing out on Relicanth, you can always console yourself with a Delibird.

While not a Generation 3 Pokemon, Delibird is currently available to catch and comes with a fast attack which includes tossing gifts at its opponent.

A new Shiny Gen 3 Pokemon has also made its debut this week, with the Snorunt variant now confirmed to be available to catch.

While Snorunt will probably not make it into your Raid team, it does evolve into Glalie in Generation 3, meaning another Shiny Opportunity.

There’s also the chance in the future that female Snorunts will evolve into Froslass, although not until Gen 4 is released.

This latest Gen 3 launch will probably mean big business for Niantic and their newly introduced Star Piece item, which can be found as part of a selection of new bundles available from the in-game store.

The pieces mean you can earn a 50% Stardust bonus for 30 minutes when activated, not bad when your looking to power-up a new team.

As part of the Christmas event, Trainers can purchase Winter Boxes for 480 coins, Great Boxes for 780 coins and Ultra Boxes for 1480 coins.

Winter Boxes contain two lots of Incense, two Incubators and five Star Pieces. Great Boxes contain four Super Incubators, ten Razzberries and ten Star Pieces.

Ultra Boxes, meanwhile, contain a whopping 25 Star Pieces, as well as eight Super Incubators, ten Pinap Berries and ten Lure Modules.

Star Pieces are particularly useful, because they grant users double stardust from all situations for 30 minutes.

Niantic has also announced a surprise festive bonus as part of the Pokemon Go Christmas event.

In order to give players a better chance of catching more Gen 3 Pokemon, Niantic has made a major change to Lure modules.

Instead of lasting just 30 minutes, Lure Modules will last for six hours.

The effect will last until January 4, which is when the Christmas event comes to an end.

"Surprise, Trainers! In celebration of the holidays, from now till January 4, Lure Modules will last 6 hours when activated!" Niantic confirmed.

"With these long-lasting lures in play, everyone’s chances of catching more Pokemon originally from the Hoenn region go up!"

Pokemon Go fans have also been given a new update regarding the upcoming EX Raids being held on Christmas Day.

Niantic have now confirmed that those situated in closed malls and other public spaces, will be cancelled.

Pokemon Go players have been confirming these changes this week, while also revealing that they are being compensated with Stardust and Premium Raid passes.

There's also a big chance that those affected will get invited to the next round of EX Raids, when they are announced.
