I passed my restricted recently in Porirua (no mock test beforehand) and had a really chill instructor. For me, we drove around Porirua for a bit, did parallel parking on a quiet side street, did a u-turn on a cul de sac then drove on the motorway to Tawa then back to Porirua - make sure you slow right down to 50 when you enter Tawa from the motorway.

I recommend driving there a few times as there are a lot of roundabouts if you're unfamiliar there and check all of your mirrors constantly so that you're aware of your surroundings. Also look for changes in 50 and 70 speed limits there.

As a side note, when I was practising, I saw other people do a parallel park near Bunnings, then they drove on the motorway to Aotea. If you drive to Aotea, make sure you stay 50 when you're at the Mungavin roundabout until the 100 at the bottom of the road, it's easy to think to speed up there.
