Coromandel Peninsula and Gisborne during Tuesday afternoon and
evening. Expect 100mm of rain in these areas, but 150mm in the ranges

Wow, you are the bearer of good news!  :-\

Just had a quick look to see what Metservice 3 day showed, Tuesday evening looks the worst for Auckland North, even though it will hang around for 2 days or so.
