No, John is referring to New Jerusalem here, not the new heaven and earth. New Jerusalem has no need of the sun and moon for God's glory is greater than the sun and moon. It will radiate throughout the city and there will be no night there (cp Re 21:25; 22:5 with Isa 60:19-20).
The sun and the moon will shine on the rest of the earth though. Scriptures teach that they will shine forever; day and night will never cease on earth (cp Gen 8:22; Psa 148:3-6; Isa 66:22-23; Jer 31:35-36; 33:20-21, 25-26).
The gates of New Jerusalem will never be shut because it will always be light there from God's radiating glory, and Christ, it's light. (City gates were only shut at night for securing the city after dark. There is no need to do this in New Jerusalem because there will never be any darkness there.)
