The first piece of Western Bay of Plenty Rugby Sub-Union championship silverware will be decided at Blake Park on Saturday when Mount Maunganui and Greerton Marist meet to decide the local Colts title.

At stake is the Ike Tangitu Cup, which is awarded to the winner of the Western Bay age group championship.

For the first time for a number of years there is a final decider with the championship having been fought out within the confines of the Baywide Colts competition in recent seasons.

Defending champions and top qualifier Mount Maunganui won through to the 2013 title decider when they defeated Tauranga Sports in a high scoring encounter last weekend, taking out the match 39-25.

By contrast Greerton Marist had to battle to the line to grab a 17-9 victory over Te Puke Sports at Te Puke headquarters.

Revenge will be added to Mount Maunganui's desire for back to back championships, after Greerton beat the Mount 26-20, in the round robin section of the competition.

Tauranga Sports could take a big step towards wrapping up the Seeka KI Western BOP first round title when they play Rangataua in the curtain raiser at Te Ariki Park.

With three rounds remaining in the first round, Tauranga Sports sit astride the top of the standings with a four point buffer.

Along with their unbeaten record the Hardy Rosebowl will also be at stake at Te Ariki Park.

There is likely to be large crowd on hand at Maharia Winiata Park when Judea square off against Arataki.

Judea has been the big improver of this year's local rugby competition.

After narrowly losing their first three matches they have strung together an unbeaten five game sequence.

However they face a formidable challenge from Arataki, who have promotion back to Baywide rugby firmly on their agenda.

In other encounters Te Puna host Rangiuru, Katikati are at home at Moore Park to Eastern Districts, Mount Maunganui should prove too strong for Te Puke Sports, while Matakana Island will be favoured to despatch Greerton Marist at Greerton Park.
