Canoeist Luuka Jones looms as New Zealand's big medal hope in Tokyo today, with the 2016 silver medallist gunning to add a second medal to her collection.
Jones produced the third best time in the K1 canoe slalom qualifiers to mark herself as a chance to repeat her success, though Australian Jessica Fox is the clear paddler to beat, having won silver in London, bronze in Rio and looking determined to make it a set in Tokyo.
While it is all pointing in the right direction for Jones, there are still many gates to pass through before the medals are awarded.
There is only one run for each paddler in the semifinals and final, so one mistake can potentially end an Olympic dream. The top 10 times in the semifinal progress to the final later in the evening.
Jones is the only realistic medal chance in action today, although the women's triathlon duo of Ainsley Thorpe and Nicole van der Kaay will try and emulate Hayden Wilde's superb bronze when they race for gold this morning. However, with both rated 151-1 chances of victory, a medal would be a stunning result.
Elsewhere, the All Blacks sevens can take a big step towards righting the wrongs of 2016. Already secured of safe passage through to the quarter-finals, the Kiwis can secure an easier path if they beat Australia early this afternoon, before facing a quarter-final at night.
It was at that stage they were dumped out in 2016, with several players from that squad returning to Tokyo for redemption.
Also in action are some sailing crews who had a perfectly pleasant time in Tokyo, with the 2016 medal-winning crews of Peter Burling and Blair Tuke and Alex Maloney and Molly Meech beginning their campaigns on the water.
