Place-names which are written as one word and have <new> as the first element tend to be pronounced with stress on the first syllable. Here are some examples:
Newbridge Newmill Newport
If the name is written with <new> as a separate word, then the first syllable gets a secondary stress and the main stress appears on a later syllable. Examples:
ˌNew ˈBrunswick ˌNew Caleˈdonia ˌNew ˈYork ˌNew ˈZealand
The name Newfoundland has the unexpected pronunciation ˈnjuːfən(d)lənd.
