How does a redox reaction between $\ce{NaClO}$ and $\ce{KBr}$ take place?

will bromide be oxidised to bromine?

$\ce{2 Br- + CIO- + H2O -> Cl- + 2 OH- + Br2}$

or will bromide be oxidised to $\ce{BrO-}$?

$\ce{Br- + CIO- -> BrO- + Cl-}$

In the pH range between 10 and 14, chloride and hypobromide are formed (DOI):

$$\ce{OCl- +Br- -> Cl- + OBr-}$$
