August has been a wet month - but whether it has been Auckland's worst for consecutive days with rain will come down to whether rain continues to fall on Wednesday.

The rain trend continued on Sunday and rain is also on the cards for Monday and Tuesday, marking 27 days in a row.

But whether it will reach 28 days - Auckland's record of consecutive days of rain - on Wednesday is still up in the air.

MetService shift meteorologist Frances Russell said more isolated showers were expected in the city of sails on Monday and Tuesday.

But so far fine weather was on the cards for Wednesday.

"It looks like it's going to be dry."

The break in rain would be short-lived with isolated showers expected to return Thursday. Friday also looked fine.

Meanwhile there was a severe weather watch in place for central New Zealand from Monday morning.

The front moved over the South Island before heading to the North Island, bringing with it strong northwesterly winds and heavy rain in Marlborough and Wellington between 6am and 10am.

The strong winds could also cause havoc in the Hawke's Bay and Wairarapa until 6pm tomorrow.

Waikato and Bay of Plenty could also expect rain early this week, while there was a heavy rain watch for the ranges of Buller early tomorrow morning and between 4am and 10am in the Tararua Range.

Russell said heavy rain could also strike southern Westland and Fiordland on Thursday as a front approached the South Island.

Meanwhile ski bunnies hoping to make the most of the fresh snow falling on Mt Ruapehu were unlikely to see much of a break in the rain and wind.

"It looks like all days have the potential for showers. Wednesday is probably one of the better forecasts with some high cloud about, but also there's a potential drizzle below 1600 metres."
