This is the adjective version of the kanji new, so it means new too.
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you:
Your parents put a newly wrapped present under the Christmas tree. You don't want to wait to see what new thing they got you so you rip it open to find they got you a raw (あら) steak. Getting a new steak is cool and all, but a raw steak is pretty gross. It's dripping blood all over the place.
