I can’t see the flowers clearly to be certain. I’m guessing maybe a cultivar in the Metrosideros genus(?). According to sources, there are about 60 species of shrubs, vines and shrubs. If this is Metrosideros, I don’t which species or cultivar this is. The link below is for Metrosideros collina, it is one of the species in the genus. Click on images to enlarge. If your plants is not of the Metrosideros genus. Make new post with closeup photo of flowers. Best wishes. https://en.wikipedia.org/wiki/Metrosideros_collina
