Kayaker Scott Donaldson has been restocked with sausage rolls by his support crew.

Kayaker Scott Donaldson has been stocked-up with sausage rolls, chicken sandwiches and Peanut Slabs for the final push to complete the first solo paddle between Australia and New Zealand.

On Sunday afternoon Donaldson was less than 100 kilometres from land and was expected to reach the Taranaki coast on Tuesday, media liaison Freddy Foote said.

"He's making good progress and has a tail wind but it's looking like it will be Tuesday rather than Monday," Foote said.

"He's in good spirits and physically he's in tip-top shape."

It is Donaldson's second attempt to make the crossing, falling an agonising 74 km short in 2014 when he was rescued in heavy seas after losing his rudder and being unable to recharge his radio batteries.

In a Facebook post on Saturday, support crew team leader Nigel Escott said their support vessel had met Donaldson early Friday morning and stayed with him for 36 hours.

"With his GPS location updated on the boat every few minutes, he was actually very easy to find and considering it was in the dark of the night."

"We've restocked Scott with some of his favourite foods, so he's enjoyed some sausage rolls, a few chicken sandwiches and some Peanut Slabs.

"We've also taken the opportunity to make sure his on-board batteries are fully charged and everything is set for this final phase of the trip."

Escott said the rendezvous with Donaldson had given the kayaker a huge confidence boost.

It is expected a north-west wind will push Donaldson toward the Taranaki coast on Sunday and a wind change to westerly on Monday will push him toward land.

It is predicted that Donaldson will now make landfall somewhere on the Taranaki coast.

"He could come into New Plymouth itself, but it could be a bit further north, such as Mokau which is around 80km north.

"We're hopeful he will make landfall on Monday or Tuesday. We will have a firm idea of location on Sunday evening," Escott said.

Scott's wife Sarah Donaldson has been waiting in New Plymouth with the couple's 8-year-old son Zac for the past week.

"This week's been highly stressful," she said.

"As he inches ever closer to land, it just becomes more and more anxiety-producing, due to the fact he got so close last time as well, and he's been out there for a while."

She said she kept in closer contact with him this time through his satellite phone, with him calling when he was available.

"It's been lovely, really lovely. We've had numerous ups and downs," she said. "It's very special to be back in New Zealand and see him nearly there."

"New Plymouth would be the best, anywhere in Taranaki would be lovely since I'm from here. But as long as he comes in I really don't care."

Foote said New Plymouth's Ngāmotu Beach remained the preferred landing site for Donaldson and he encouraged the public to be there to welcome him in.

"He's aware of all of the support online and is pretty pumped about that."
