Prior to the coronation show, there was a tune-up pageant for selected delegates (or all of the delegates in 2019) at Hannah's Beach Resort (2012-2017 except 2015) or at Jesse M. Robredo Coliseum (2019). These winners of the tune-up pageant made the cut and majority of them ended up winning Miss Earth title.

Miss Earth Hannah's Beach Resort 2013: Alyz Henrich of Venezuela (Miss Earth 2013 winner)

There was no tune-up pageant in 2015 because the pageant was held in Austria while there is no tune-up pageant in 2018 since Carousel and Hannah's Beach Resort ended their sponsorship deal. The 2019 coronation show was supposed to held at Naga but it relocated to Cove Manila at Okada Manila instead they used as the final medal events for two remaining groups with concurrent tune-up pageant just like at Hannah's Beach Resort in the past.
