STRAIGHT UP: Former New Zealand cricketer Adam Parore hopes to reach the summit of Mt Everest this weekend.

Former New Zealand cricketer Adam Parore is just days away from the summit of Mt Everest having spent months training and acclimatising.

Parore, who is climbing the world's highest mountain to raise funds for the Make-A-Wish Foundation, has overcome altitude sickness and the disappointment of a first attempt in which his climbing group was forced to turn back because of bad weather.

The Aucklander, who represented New Zealand in cricket for more than a decade, has been regularly updating a Facebook page while in the Himalayas.

His latest post was on Sunday, saying the group was heading off at two in the morning "for another crack at the big girl". Parore said the group was expecting to summit about midday on Saturday (NZ time) "all things being equal".

"Same drill as last week except we are hoping the weather window holds this time. I was just thinking that it all seemed a little easy – not any more. Everest the hard way we're calling it. Fingers crossed for blue skys and happy trails."

Former partner Sally Ridge posted a message saying: "Kids loved talking to you and send more kisses. Be safe."

In an earlier attempt, the group, which includes a guide who is one of Parore's close friends, had to turn back because of 50kmh-to-60kmh winds and worse weather forecast for what was to have been their summit day, May 14.

The group returned to base camp and Parore wrote a post on Facebook of the ordeal.

"All up a 16-hour day – Sherpa-esque. 1000m up, 2000m down and about 15km covered all up. 100 calories intake, about 20,000 expended. I was a bit tired after that. Unsurprisingly I slept like a dead man. Strangely I woke yesterday morning feeling 100 per cent, like I normally do at sea level. Go figure? I feel better now than before we left for the summit."

Parore left New Zealand on March 27 for Nepal to spend a month acclimatising at the Mt Everest base camp before trying to climb to the summit. Since May last year he has been scaling some of New Zealand's and the world's highest mountains to prepare for the climb.

He has battled altitude sickness since arriving at Everest base camp, at a height of more than 5000 metres.

Parore has said he hopes to raise $100,000 for the Make-A-Wish Foundation. The money will go into a wish pool to be used for granting the wishes of terminally ill children.
