Further to my earlier comment - the Canon R seems to be the only mirrorless atm to have a shutter that closes over the sensor when changing lenses (camera has to be turned off), and hence protects from dust, salt spray, etc.
In Wellington there's a retail store - Wgtn Photographic Supplies that rents out various camera gear - they may have a mirrorless camera or two to rent. In Auck there are a few places to try for rental gear - Kingsize Studios or White Studios are a couple I can think of.
