A trough is expected to move slowly east over the country during Friday, Saturday and early Sunday, bringing rain to many parts of the country. A Watch is currently in force for northern Westland, Buller, Nelson, Mt Taranaki, Northland, Coromandel Peninsula and the Bay of Plenty, for the possibility of rainfall amounts exceeding warning criteria during this time - indicated as a high risk on the chart. In addition, there is a moderate risk of heavy rain about Auckland, Waikato, Waitomo, Taumarunui, Taupo, Wanganui and Taihape from Saturday to early Sunday as this trough passes.
On Sunday, a ridge of high pressure is expected to move onto the country from the west, followed by another trough, which is forecast to move east over New Zealand during Monday and Tuesday. Another burst of rain is expected with this trough, followed by a cooler southerly change late on Tuesday.

Lucky Bett, should be a good game.
We contemplated heading back down but decided against it with the weather lousy again.
We were soaked last week going to the All Blacks game.
Enjoy your visit Bett and yes sunshine will be nice :)

A front over Bay of Plenty, preceded by moist northerlies and heavy rain, is forecast to move eastwards today and should clear the North Island this evening. The heavy rain warning remains in force for Bay of Plenty east of Te Puke, where a further 60-90mm is expected about the ranges through to 6pm on top of rain that fell overnight. Rivers and streams are likely to rise and surface flooding and slips are possible.
Farther west in Bay of Plenty and for Coromandel Peninsula, heavy rain has now eased and warnings there are lifted. Note however, showers are expected today, especially this afternoon and early evening when some may be heavy with isolated thunderstorms.
