Police were at the scene yesterday morning and are continuing their investigation.
Napier Old Boys Marist club chairman Terry Gittings said he was frustrated at the situation because the club always encouraged members not to drink and drive and this hurt people who were doing the right thing.
"It's a shame ... it's disappointing that some people came through and decide to break into vehicles."
He was aware of two vehicles owned by club members that were broken into.
A review of surveillance footage showed the incidents appeared to happen at about 5am, well after the clubrooms were locked at 12.30am.
