• Related近代的きんだいてきNeutralModern in character, mostly for institutions and facilities; different from 「新規」's sense of newly added.

• Related事新しいことあたらしいWrittenRare, written/formal prose: novel in a way that differs from before, sometimes with a hint of affectation, as in 「事新しく言う」; seldom used in daily life.
• Antonym既存きそんNeutralThe direct opposite: already existing, as in 「既存顧客」 or 「既存店」; the two are often paired in business contexts.
• Antonym従来じゅうらいNeutralConventional, what has been the case all along; also works as an adverb. Pairs against 「新規」 in old-versus-new contrasts, as in 「従来の方法」.

For everyday 'new', use 「新しい」. 「新規」 is for newly added customers or business, or new practices unlike anything before, as in 「新規登録」 and 「新規な趣向」. In written prose, choose 「新た」; for strikingly original ideas or designs, 「斬新」. The opposites are 「既存」 and 「従来」.
